With throughput demands continually increasing, and an ongoing need for more detailed sample information, PerkinElmer systems are setting the standard for speed and productivity in all areas of lubricants analysis: 1.) Wear metals analysis, 2.) Oil condition monitoring and 3.) Confirmatory testing. Modular and scalable, each solution can adapt as your needs change—no matter what the size of your organization or the demands of your application
The analysis of soils for elemental contents presents challenges during the sample preparation step. A common method for preparing a soil sample for inorganic elemental analysis involves digesting the soil sample in an acid that is heated to near-boiling to extract the elements for analysis. When using open vessels in heating blocks, this extraction method typically takes four hours or more to complete. The sample must then be centrifuged or filtered to remove solid particles prior to analysis. The use of a microwave digestion system can speed this up significantly by completing the acid digestion in less than 50 minutes.
The London Metal Exchange issues specifications for a number of different metals in several grades. This work focuses on the analysis of lead of different purities with PerkinElmer’s Avio® 500 ICP Optical Emission Spectrometer (ICP-OES), using “Special Contract Rules for Standard Lead1” as a guideline for the analytes and concentrations.
Globally, heavy machinery is used in construction, mining, and a variety of other areas. As the scale of the operations increase, the size, complexity, and cost of the equipment also increase, meaning that breakdowns can be costly, both in equipment repair and lost revenue. As a result, preventive maintenance is paramount. Lubricants are among the key fluids that can be tested, especially the oil used in engines. By monitoring the elemental concentration of the oil or other lubricants (hydraulics, transmission, gear), the status of that compartment can be determined.
The London Metal Exchange (LME) issues specifications for a variety of purities for different metals. This work focuses on the analysis of contaminants in nickel with PerkinElmer’s Avio® 500 ICP Optical Emission Spectrometer (ICP-OES), using “Special Contract Rules for Primary Nickel” as a guideline for the analytes and required concentrations.
The analysis of trace metals in metallurgical matrices also presents a challenge for ICP-OES: spectral interferences. Many elements have a large number of emission lines (i.e. approximately 20,000 for iron), which increases the potential for spectral interferences. This effect is compounded in metallurgical samples, where the matrix element(s) are present at high levels due to the minimal dilutions used.
When blending base oils and additives for use as lubricants, it is important to know and control the concentrations of certain elements for optimal performance and longer engine life. This work will focus on the analysis of additives in new oils using PerkinElmer’s Avio™ 200 ICP Optical Emission Spectrometer (ICP-OES), which overcomes limitations of other ICP-OES systems and X-ray analyses.
With heavy machinery, it is important to assess its status during operation to prevent breakdowns and costly repairs. A key aspect is monitoring the status of the oil or lubricants used to lubricate various components such as engines, transmissions, gearboxes and many other important areas: if the oil degrades too much or becomes highly contaminated, it can damage various components. Because of its importance, ASTM created a method for the analysis of in-service oils: method D5185.
This work focuses on the analysis of wastewaters following the guidelines provided in U.S. EPA Method 200.7. The U.S. Environmental Protection Agency (EPA) developed Method 200.7 for the determination of metals and trace elements in waters and wastes by ICP-OES, with the current version being Revision 4.4.1 While the scope of this method allows it to be applied to a variety of sample types, a common application is wastewater analysis.
Sample preparation is one of the most critical steps in your analytical process. Often accounting for 60% of your analytical timetable, it has a fundamental impact on laboratory throughput and analytical performance. Any errors within the sample preparation process will undermine the quality of your food data at all subsequent stages of your analysis. Here are five tips to improving your sample digestion for food samples.
