Fundamental Infrared Spectroscopy
By Hue Phan, MIDAC Corporation
Spectroscopy is the study of the interaction of electromagnetic radiation with a chemical substance. The nature of the interaction depends upon the properties of the substance. When radiation passes through a sample (solid, liquid, or gas), the molecules of the substance leading to the molecular vibrations absorb certain frequencies of the radiation. The frequencies of absorbed radiation are unique for each molecule, which provide the characteristics of a substance.


Analysis Of Potential Genotoxic Acrylamine And Aminopyridine Impurities In Active Ingredients
By Gerd Vanhoenacker, Frank David, and Pat Sandra, Research Institute for Chromatography, Belgium
This application note illustrates the possibilities of the Agilent 1290 Infinity LC system and the Agilent 6460A Triple Quadrupole Mass Spectrometer for quantitative analysis of potential genotoxic impurities (PGIs) in active pharmaceutical ingredients (APIs). A generic approach was used to determine arylamine and aminopyridine PGIs in selected APIs. The influence of column length and mobile phase composition on the recovery of these impurities in real samples were investigated.

An Introduction To Chemical Adsorption Analytical Techniques And Methods
Catalysts are used in a variety of applications from the production of consumer goods to the protection of the environment. Chemical adsorption ("chemisorption") analysis techniques provide much of the information necessary to evaluate catalyst materials in the design and production phases, as well as after a period of use.

Determination Of Concentrations In Samples With Three Components
Anton Paar Digital Density Meters have been used for decades to accurately determine the concentrations of many binary liquids. However, a density measurement is not enough information to calculate quantities in samples containing more than two species.

MiniModule® Membrane Contactors
MiniModule Membrane Contactors from Membrana come in three sizes. The only difference is size, which allows them to handle different capacities.
