Introduction Professor Francesco Regoli, of the Polytechnic University of Marche, provides an overview of the risks posed by emerging pollutants such as microplastics and pharmaceutical compounds in the marine environment. Professor Regoli discusses the …
APPLICATION NOTE
Introduction There are many types of nanocomposites - such as epoxy, polymer, and carbon tube materials. Nanocomposites are made from embedding materials into one another with at least one of the phases showing dimensions in the nanometer range. This …
APPLICATION NOTE
Introduction Fourier Transform Infrared (FT-IR) Spectroscopy is used routinely in the analysis of both new and in-service lubricants to determine chemical attributes such as oxidation, nitration, sulfation, water and soot. FT-IR microscope is a valuable …
APPLICATION NOTE
Introduction Polybutadiene rubbers are used for the fabrication of car tires, wiper blades, gaskets, and other products where the ability to deform and return to the original shape are important. The glass transition temperature is of vital importance …
APPLICATION NOTE
Introduction The main source of elements and minerals has traditionally been mining from geological deposits in the earth. While an effective strategy for many elements, it is not the most efficient for elements which are not naturally abundant at high …
APPLICATION NOTE
Introduction This Application Brief demonstrates the ability of PerkinElmer's LC 300 instrument platform, and SimplicityChrom™ chromatographic data system (CDS) software to successfully meet the United States Pharmacopeia (USP) performance requirements …
APPLICATION NOTE
Introduction The recent emergence of mRNA-based vaccines and therapies has made clear the need for reliable analytical methods that can successfully identify, characterize, and quantify mRNA. This chemical instability demands a deeper understanding of …
APPLICATION NOTE
Introduction Organic solvents are commonly used in the production of active pharmaceutical ingredients (API) and pharmaceutical products. The solvents are used for varying purposes including as synthesis reaction media, in the separation and …
APPLICATION NOTE
Introduction USP 467 is a widely used method for the determination of residual solvents in pharmaceutical products using gas chromatography (GC) with a flame ionization detector (FID). Due to the prescribed GC method settings, USP 467 has a long run …
APPLICATION NOTE
Introduction There are a wide variety of characterization techniques which may be used to identify drugs of abuse, including infrared spectroscopy, Raman spectroscopy, mass spectrometry, gas chromatography, x-ray diffractometry, immunoassays and urine …
ARTICLE
Introduction Audit trails are becoming a topic of increasing awareness in the pharmaceutical industry, due not only to increased focus on regulatory compliance, but also the additional complexity that often comes with enhanced technologic capabilities …
Library Pages
Introduction The analysis of triacylglycerols by gas chromatography (GC) in their native state is challenging, largely due to their poor volatility and thermal decomposition in hot injector ports. To improve their properties for GC and to provide a …
APPLICATION NOTE
Introduction Polyethylene glycol (PEG) is a polyether compound derived from petroleum and one of the most popular polymeric materials with diverse industrial/biological/medical applications. PEG is routinely synthesized by polymerizing ethylene oxide, …
APPLICATION NOTE
Introduction Vitamins are involved in a variety of different physiological processes and must be assimilated with the daily nutrition as they cannot be synthesized within the human body. The biochemical functions of vitamin C (ascorbic acid) are mainly …
APPLICATION NOTE
Introduction Tobacco specific nitrosamines (TSNA) are a group of chemicals found in tobacco, smokeless tobacco, and tobacco smoke. They are widely considered to be among the most important arcinogens in tobacco products and cigarette smoke. Tobacco …
APPLICATION NOTE
Introduction Most of the copper (Cu) concentrates produced globally contain some impurities, which can affect the price as copper concentrates containing high levels of impurities are not accepted by some smelters. To permit treatment and to maximize …
APPLICATION NOTE
Introduction Quantitative analysis of cell culture media components is a critical step in upstream bioprocess development. A comprehensive and quantitative understanding of cellular metabolic components could lead to a greater understanding of the …
APPLICATION NOTE
Introduction Determination of nucleic acids is a common procedure in most molecular laboratories. Accurate and rapid method to quantify DNA is essential to obtain reliable outcomes. Fluorescence spectroscopy offers a simple yet highly sensitive …
APPLICATION NOTE
Introduction Growing health concerns regarding Per- and polyfluoroalkyl substances (PFAS) and their prevalence in consumer goods and the environment indicates a critical need to perform existing and upcoming regulatory methods efficiently and reliably …
APPLICATION NOTE
Introduction Chiral supercritical fluid chromatography (SFC) is the primary tool for the separation of enantiomers in support of drug discovery efforts. SFC uses a simple mobile phase system consisting of non-toxic CO2 and an organic modifier, typically …
