Introduction The purpose of this study is to demonstrate the proximate analysis of two standard samples using the STA and show that the performance is easily able to allow this moderate cost, small profile and sturdy instrument to be used for this type …
APPLICATION NOTE
Introduction Infrared spectroscopy is particularly suitable for the identification of materials, even when the differences between the materials are subtle variations in complex mixtures. In this note we demonstrate that biodiesel from several common …
APPLICATION NOTE
Introduction BPA or bisphenol A is well known for its effect on human health and is a concern in two common polymers - PVC and Polycarbonate. BPA is used in PVC production as a polymerization inhibitor, however residual BPA monomers may remain after …
APPLICATION NOTE
Introduction Thermogravimetric analysis (TGA) is one of the members of the family of thermal analysis techniques used to characterize a wide variety of materials. TGA provides complimentary and supplementary characterization information to the most …
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 …
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 …
APPLICATION NOTE
Introduction Herbal lifestyle products are widely used as alternatives to medicines around the world, with as many as 80% of people using them as a primary source of healthcare in developing countries. These treatments are commonly regarded by …
APPLICATION NOTE
Introduction Since early 2018, manufacturers of pharmaceutical products are mandated to comply with USP <232/<233> requirements around the analysis of elemental impurities in medications. This work demonstrates the ability of PerkinElmer’s Avio® 220 Max …
APPLICATION NOTE
Introduction With the implementation of USP <232>/<233> for the analysis of elemental impurities in finished drug products, it is important for manufacturers to monitor the metal content of the final products to be in compliance. This work demonstrates …
