Glycerol may be used as a reference standard in the determination of glycerol in samples of beer using gas liquid chromatography (GLC). It is a simple polyol compound, which is obtained as a by-product of soap and bio-diesel industries. It is odourless, colour-less, viscous in nature, and exists as a sweet tasting liquid. It can be derived naturally as well as from petrochemical feedstock.
Glycerol has been used as:

Syringe filters are single-use, membrane-based devices used for the removal of particulate impurities from liquid and gas samples prior to analysis by methods such as HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing. Proper filtration of samples improves the quality and consistency of analytical results and decreases instrument downtime.
