Ion chromatography (IC) is an analytical technique used to separate and quantify ionic and polar analytes. IC has become widely accepted by the pharma industry and regulatory bodies for an expanded range of applications like water quality and chemical analysis. It has qualified in recent years to analyze pharmaceuticals. The United States Pharmacopeia-National Formulary (USP-NF, US Pharmacopeia (USP)), the driving standardization body for (bio)pharmace

The medical industry is a new frontier for Raman spectroscopy. In the past few years, Raman has been used in dental and cancer studies, and is now building on this success by extension into Point-of-Care (POC) applications. This article gives an overview of some very new and exciting research into the use of Raman spectroscopy for the detection of cancerous tissue, biomarkers of disease, and pathogens that cause disease. 

The saying «cleanliness is next to godliness» has been around for centuries. The implication is that the act of keeping our clothing, living spaces, belongings, and of course our own bodies clean elevates us above other animals, and by extension, our own baser instincts. Aside from this, it is well-known that diseases flourish in unclean conditions, and it is in our best interest as a society to keep things clean. Therefore, cleaning agents (e.g., detergents and sanitizers)

Ion chromatography and sample filtration go hand-in-hand since this pretreatment step is advised for the majority of sample matrices. It is essential to avoid injecting particles, algae, or bacteria into the IC system, as these can jeopardize both the instrument and the separation column. Samples are often prepared manually, for example by using filtration or centrifugation to remove contaminants and interfering matrix components. A more efficient way to prepare samples for IC ana

Quality control of hair, skin, and dentalcare products continues to increase in importance for producers. Aside from safeguarding our health, it is equally important to avoid the sale of out-of-specification products. Product recalls are very expensive and have a lasting effect on a company’s reputation. Therefore, intensive testing of these different care products is essential before they are brought to the market. This article shows how utilizing near-infrared spectroscopy (NIRS) for
