The OilExpress 4 system adapts to your laboratory’s needs, from dozens to thousands of samples per day. Its modular design makes it possible to scale up your sample throughput or separately utilize the oil dilution capabilities in busy laboratories that are using ICP analysis. The system minimizes your operational costs by reducing instrument downtime, increasing throughput to reduce cost per sample, and offering significant savings from decreased solvent waste.
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
There is a growing body of evidence showing that there are significant differences between some nanomaterials and their non-nanoscale counterparts. What those differences portend raises many new questions about their potential to cause harm to human health and the environment.
Analyzing single nanoparticles with ICP-MS requires a different approach than measuring dissolved elements. This work describes the theory behind single-particle ICP-MS measurements, drawing comparisons and differences with analyzing dissolved elements.
In the textile industry, the use of titanium dioxide (TiO2) nanoparticles (NPs) is increasing due to their ability to provide UV protection, increase the hydrophilic nature of fabrics, provide antibacterial characteristics, and reduce odors. This work studies the release of TiO2 NPs from various commercial textile products which do not advertise that TiO2 NPs have been added.
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.
Microwave sample preparation provides an efficient and clean sample preparation for multi-element analytical techniques such as ICP-OES and ICP-MS. As Microwave assisted digestion has evolved, so have the methodologies. EPA method 3052 is designed for the “total” analysis in a variety of matrices including soil, sediments, sludge, oils, biological and botanical materials. This method is the most versatile and has been well proven. It allows variations in reagents and methodology, making it ideal for a variety of matrices and elements. The variability of this method also requires a basic understanding of digestion chemistry.
The United States Pharmacopeia (USP) has announced that its new standards for elemental impurities in drug products has been implemented since January 1, 2018. General Chapters <232> and <2232> specify the list of elements and their permissible daily exposure (PDE) limits based on the route of administration.
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.
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.
