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
In this work, we demonstrate that PerkinElmer's NexION® 2000 ICP-MS, with its unique RF generator and ion optics, coupled with the Syngistix™ Nano Application Software Module, can be used to accurately measure and characterize NP sizes of 10 nm and smaller, both alone and in a mixture of NPs of various sizes.
When mining for precious metals, ores are extracted from the ground and subjected to various sample preparation procedures in order to remove the metals of interest. A commonly used procedure to isolate metals from the ore is fire-assay, which leaves a matrix-free “button” of the metal. This work will focus on the analysis of precious metals in simulated digested precious metal buttons, with an added emphasis on assessing the lowest limits which can be accurately measured.
幸运8平台彩票This work demonstrates a robust method using SP-ICP-MS technology to detect CeO2 NPs which were extracted from soil samples with tetrasodium pyrophosphate (TSPP). Over the past few decades, engineered nanoparticles (ENPs) have been increasingly used in many commercial products. As a result, more and more ENPs have been released into the environment, which raises concerns over their fate, toxicity and transport therein.
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.
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.
This work has demonstrated the ability of the NexION 2000 ICP-MS to analyze both natural and drinking water samples in Standard (i.e. non-cell) mode, in accordance with U.S. EPA Method 200.8. Accuracy has been demonstrated through the analysis of several reference materials and spike recoveries, with stability of at least nine hours. Method detection limits allow for trace-level determinations, while the ability to selectively suppress user-defined isotopes also allows the measurement of analyte levels usually only possible by ICP-OES or Flame AA. The NexION 2000 provides a comprehensive solution to the challenge of U.S. EPA Method 200.8 and other drinking and natural water analytical requirements across the globe.
幸运8平台彩票A major challenge in the analysis of food samples is the extremely low analyte levels and the very high matrix levels. For many years, graphite furnace atomic absorption spectroscopy (GFAAS) has been a reliable technique and the preferred method for this analysis, especially for the determination of Cd and Pb. This work will focus on the use of GFAAS for the determination of lead and cadmium in a variety of food samples.
Through the years, both industry and analytical instrumentation have advanced. With the development of new chemicals and processes, new pollutants may enter the environment. However, the capabilities of analytical instruments have also increased, allowing the measurement of ever lower levels of environmental contaminants, as well as new pollutants.
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.
幸运8平台彩票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.
