APPLICATION NOTE
Introduction Mid-infrared (MIR) microscopy is a broadly employed chemical identification tool that is used to complement traditional light microscopy. In recent years we have seen an explosive growth in the applications of the FT-IR Imaging Microscope …
APPLICATION NOTE
Introduction Bottled water is marketed as being the clean and pure alternative to drinking tap water. However, there is increasing opposition to the use of single-use plastic bottles and the fact that they end up in the environment either as intact …
APPLICATION NOTE
Introduction Cavity-enhanced absorption spectroscopy (CEAS) has similarities with the better known cavity ringdown technique (CRDS) which measures the signal decay as a laser pulse emerges through one of the mirrors after successive reflections. By …
APPLICATION NOTE
Introduction Glycerol (or glycerin) is a colorless, odorless liquid that is generally safe for human exposure and consumption. It has many uses in the food, pharmaceutical and personal care industries due to its range of versatile properties allowing it …
APPLICATION NOTE
Introduction Olive oil is an increasingly popular food product worldwide, with global production exceeding 3.0 million tons in 2011 and showing steady annual growth. Despite these huge volumes, however, margins are relatively small in olive oil …
APPLICATION NOTE
Introduction This study describes the injection, separation, and identification of 16 drug compounds in less than 10 minutes using portable gas chromatograph-toroidal ion trap mass spectrometry (PerkinElmer, Torion T-9 Portable GC/MS) combined with a …
APPLICATION NOTE
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 …
