It’s increasingly clear that quality-conscious organizations can’t afford to hand off responsibility for metals verification. The inspection of the metal makeup of incoming and outgoing components is a critical quality control (QC) task for companies worldwide.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">While the focus of this article is on steels, non-ferrous alloy users are confronted with similar situations and are required to perform similar testing tasks. Some steel<span> </span><a href="http://www.skyray-instruments.net/" target="_self">products</a><span> </span>are easy to analyze. For many suppliers and end users, testing with a handheld X-ray fluorescence (XRF) or simple handheld optical emission spectrometry (OES) analyzer is adequate. Their size and relatively low initial costs have created great interest in these handheld analyzers, which produce fast results for on-the-spot alloy identification, grade sorting or verification.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">In many cases, the presence or absence of an alloying element in a steel component is critical to its performance but impossible to detect by physically inspecting the item. Positive material identification (PMI) has become accepted practice for the process and equipment supply industries. The industry-standard approach for achieving efficient PMI is via elemental analysis of the materials.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><a href="http://www.skyray-instruments.net/metal-analyzer/slag-analyzer/" target="_self">Slag Analyzer</a><span> </span>presents a uniquely compact and reliable WDXRF platform configured with Thermo Scientific SmartGonio for analysis of slags and pig iron.

At the bare minimum, the lubricants in those components should be analyzed regularly. (Ideally, all lubricants in use at your facility should be tested regularly.)</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Register the equipment with the lab. This will help the lab identify appropriate tests for your specific application. Registration also facilitates trending.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Use proper sampling procedures. Improper sampling may produce erroneous test results. Problems could be missed and go untreated, leading to costly problems later. Or conditions may be misdiagnosed, resulting in incorrect, unnecessary and money-wasting actions being taken to correct a nonexistent issue.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Provide complete and accurate information with each sample you submit to the lab. Missing or inaccurate information may lead to a misdiagnosis. Complete all fields on the submission form, including the specific lubricant in use, the component it services, the hours the oil has been in use, and more. Also ensure that the information is legible to help avoid misinterpretation.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Submit samples promptly to the laboratory for analysis. Although a delay inherently has virtually no effect on the sample itself, it does increase the potential for contamination. Also, the condition of the oil in use in the equipment will continue to change over time. The more time that passes between when the sample is taken and when it is analyzed, the less alike the sample will be to the fluid still flowing in the machine. Therefore, the results of the analysis will have less relevance.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Review and respond to test results appropriately. Promptly review the analysis documentation to determine what, if any, action is necessary.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Use oil analysis regularly, not just when you suspect a problem. As part of a preventive maintenance program, regular oil analysis establishes a baseline for monitoring the condition of your lubricants and the components in which they are used. Much like routine, periodic medical screenings, the regular collection of analysis data over time may help identify trends and spot potential complications in early stages, so that they can be corrected and not become big problems.</p><h2 style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">How do we measure static gel strength development?</h2><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Historically, the SGS of a cement slurry was determined by a method using a couette-type rotational viscometer.

It’s increasingly clear that quality-conscious organizations can’t afford to hand off responsibility for metals verification. The inspection of the metal makeup of incoming and outgoing components is a critical quality control (QC) task for companies worldwide.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">While the focus of this article is on steels, non-ferrous alloy users are confronted with similar situations and are required to perform similar testing tasks. Some steel<span> </span><a href="http://www.skyray-instruments.net/" target="_self">products</a><span> </span>are easy to analyze. For many suppliers and end users, testing with a handheld X-ray fluorescence (XRF) or simple handheld optical emission spectrometry (OES) analyzer is adequate. Their size and relatively low initial costs have created great interest in these handheld analyzers, which produce fast results for on-the-spot alloy identification, grade sorting or verification.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">In many cases, the presence or absence of an alloying element in a steel component is critical to its performance but impossible to detect by physically inspecting the item. Positive material identification (PMI) has become accepted practice for the process and equipment supply industries. The industry-standard approach for achieving efficient PMI is via elemental analysis of the materials.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><a href="http://www.skyray-instruments.net/metal-analyzer/slag-analyzer/" target="_self">Slag Analyzer</a><span> </span>presents a uniquely compact and reliable WDXRF platform configured with Thermo Scientific SmartGonio for analysis of slags and pig iron.

At the bare minimum, the lubricants in those components should be analyzed regularly. (Ideally, all lubricants in use at your facility should be tested regularly.)</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Register the equipment with the lab. This will help the lab identify appropriate tests for your specific application. Registration also facilitates trending.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Use proper sampling procedures. Improper sampling may produce erroneous test results. Problems could be missed and go untreated, leading to costly problems later. Or conditions may be misdiagnosed, resulting in incorrect, unnecessary and money-wasting actions being taken to correct a nonexistent issue.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Provide complete and accurate information with each sample you submit to the lab. Missing or inaccurate information may lead to a misdiagnosis. Complete all fields on the submission form, including the specific lubricant in use, the component it services, the hours the oil has been in use, and more. Also ensure that the information is legible to help avoid misinterpretation.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Submit samples promptly to the laboratory for analysis. Although a delay inherently has virtually no effect on the sample itself, it does increase the potential for contamination. Also, the condition of the oil in use in the equipment will continue to change over time. The more time that passes between when the sample is taken and when it is analyzed, the less alike the sample will be to the fluid still flowing in the machine. Therefore, the results of the analysis will have less relevance.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Review and respond to test results appropriately. Promptly review the analysis documentation to determine what, if any, action is necessary.</p><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Use oil analysis regularly, not just when you suspect a problem. As part of a preventive maintenance program, regular oil analysis establishes a baseline for monitoring the condition of your lubricants and the components in which they are used. Much like routine, periodic medical screenings, the regular collection of analysis data over time may help identify trends and spot potential complications in early stages, so that they can be corrected and not become big problems.</p><h2 style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">How do we measure static gel strength development?</h2><p style="color: rgb(0, 0, 0); font-family: "Microsoft YaHei"; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Historically, the SGS of a cement slurry was determined by a method using a couette-type rotational viscometer.
