Market Profile: Continuous Flow Analysis and Discrete Analysers
In continuous flow analysis (CFA), a sample is injected into a flowing carrier solution passing rapidly through small-bore tubing. The sample is mixed with a reagent, which reacts with the sample to develop a color and determine the sample concentration. The use of carefully controlled flow conditions ensures that the color development reaction is reproducible, so that the color measurement need not wait until the reaction has gone to completion.

Market Profile: Volatile Organic Extraction
March 1st 2019Gas chromatography (GC) sampling of volatile organic compounds (VOCs) is typically done by headspace, purge and trap, or thermal desorption instruments. Headspace sampling is the simplest of the techniques, where a vapor sample is taken from the space above the liquid sample in a GC vial.
