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.
Compliance with California’s Proposition 65 for the monitoring of lead (Pb) in calcium-based antacid medications and dietary supplements requires the analytical methodology to demonstrate detection limits below 0.05 µg/g in the solid material. The analytical capabilities of Inductively Coupled Plasma Mass Spectrometry (ICP-MS) make it the most suitable technique for performing lead determinations at these low levels on a routine basis.
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.
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.
Cisplatin, carboplatin, and oxaliplatin are the most widely used of platinum-based cancer chemotherapy drugs in the Western world. Cisplatin's effectiveness is due to its ability to bind to the DNA, resulting in DNA-platinum (Pt) adducts, which bend the DNA. The cells must then repair the DNA damage, otherwise DNA replication is blocked resulting in cell death. Many cancers are initially sensitive to platinum-based treatment, but patients frequently relapse with tumors displaying resistance to further cisplatin therapy.
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.
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.
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.
Nanoparticles (NPs) have been of significant interest over the last two decades as they offer attractive benefits for drug delivery to overcome limitations in conventional chemotherapy. Nanoparticles can be engineered to carry both drugs and imaging probes to simultaneously detect and treat cancer. They may also be designed to specifically target diseased tissues and cells in the body. A number of nanoparticlebased cancer therapeutics have been approved for clinical use and/or are currently under development.
