IR Microscopy That Overcomes Your Biggest Challenges And Your Smallest … Introduction PerkinElmer Spotlight™ 150i and 200i are high-performance FT-IR microscopy systems designed to meet the needs of lab scientists faced with analyzing increasingly …
APPLICATION NOTE
Introduction Measurement of metanephrines and normetanephrine in plasma is challenging due to the low physiological concentrations, their hydrophilic nature1, and time consuming traditional sample preparation. With use of the PerkinElmer QSight® 220 …
APPLICATION BRIEF
Introduction Inductively coupled plasma mass spectrometry (ICP-MS) is the technique of choice for the analysis of food materials. This is thanks to its ultratrace detection capabilities, ideal for the determination of low-level contaminants, such as Pb, …
APPLICATION BRIEF
Introduction Compositional analysis of liquid animal feed is an important step in verifying proper nutritional value at the mixer and prior to shipment to customers. Nutritional information is vital to farmers when formulating feeding strategies. The DA …
APPLICATION NOTE
Introduction Explosive materials are composed of energy-rich substances that release stored energy through a series of violent chemical processes upon ignition. The chemicals responsible for these explosive reactions are typically unstable without the …
APPLICATION NOTE
Introduction The production of fertilizer is a key industry for a country's agricultural sector, with the main benefit of increasing crop productivity. The primary elements of interest in fertilizers are categorized into four classes: primary nutrients, …
APPLICATION NOTE
Introduction Pharmaceutical and Personal Care Products (PPCPs) are an emerging environmental concern, and include human and veterinary prescription and over-the-counter medications, sunscreens, lotions, soaps, and insect repellants. These commonly …
APPLICATION NOTE
Introduction Volatile organic compounds (VOCs) are a series of compounds with high vapor pressure and boiling points from 50 to 250 degrees centigrade. These characteristics lead to the tendency for large numbers of molecules to evaporate, or …
APPLICATION NOTE
Introduction Aniline and aniline derivatives are widely used as raw materials and intermediates in the polymer, rubber, dye, pesticide and pharmaceutical industries. Unintended releases of aniliane or its derivatives into the environment pose a serious …
APPLICATION NOTE
Introduction 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. Because this process is so crucial, ASTM developed a …
APPLICATION NOTE
Introduction 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, …
APPLICATION NOTE
Introduction The combination of Thermogravimetric Analysis with Infrared Spectroscopy (TG-IR) is the most common type of evolved gas analysis. Thermogravimetric Analysis (TGA) accurately measures the percentage weight loss of a sample as a function of …
APPLICATION NOTE
Introduction This work investigated the transfer of Ag and CuO nanoparticles from consumer products via simulated dermal contact by using textile wipes as a surrogate using PerkinElmer’s NexION® ICP-MS single particle analyzer with the unique Syngistix™ …
APPLICATION NOTE
Introduction Particle counting is becoming a more routine tool for lubricant condition monitoring and maintenance programs to better identify particles of certain sizes and concentrations that can contribute to machine failure. In-service oils and other …
Q&A
Introduction Of all the non-scientific issues your laboratory must deal with, none is more pressing than your approach to services procurement and consolidation – particularly in multivendor environments. Whether you’re consolidating facilities due to a …
APPLICATION NOTE
Introduction Ethanol is often utilized in commercial denatured fuel products to improve performance, and does not exhibit many of the environmentally dangerous characteristics of tetraethyl lead (TEL) and methyl-tert-butyl ether (MTBE). The primary …
APPLICATION NOTE
Introduction The production of electronic devices is a complex process that requires the use of ultra-pure chemicals during the manufacturing steps. High-purity-grade sulfuric acid (H 2 SO 4 ) is generally used for cleaning components and etching all …
APPLICATION NOTE
Introduction Near-infrared (NIR) spectroscopy is an important technique for materials checking at various stages of the manufacturing process, but is particularly useful at the raw materials inspection stage. Raw materials come in a variety of physical …
APPLICATION NOTE
Introduction The exact number of counterfeit medicines produced/consumed each year is difficult to determine due to the usually illegitimate methods by which they are distributed. However, the scale of the problem can be represented by the fact that 20 …
