Chromatography

Chromatography plays a crucial role in many pharmaceutical industries and also within the chemical and food industry. Environmental testing laboratories generally want to spot for very small quantities of contaminants like PCBs in waste oil, and pesticides. The Environmental Protection Agency makes the tactic of chromatography to check beverage and to watch air quality. Pharmaceutical industries use this method both to organize huge quantities of extremely pure materials, and also to analyse the purified compounds for trace contaminants.
