Macherey-Nagel GC Capillary Column OPTIMA Biodiesel G ID: 0.25 mm, length: 10 m
High performance capillary columns for gas chromatography (GC). The capillary column OPTIMA BioDiesel G allows determination of free glycerol and residues of mono-, di- and triglycerides in FAMEs intended as additives for mineral oils. The procedure can be applied for FAMEs from rapeseed oil (canola oil), sunflower oil and soy bean oil. Glycerol as well as mono- and diglycerides are derivatized to more volatile substances by addition of MSTFA in the presence of pyridine.Meer tonen
