For determination of solvent residues (O.V.I.)
 

ROTISOLV® Headspace Grade Solvents

for analyses of organic volatile impurities (O.V.I.)

Headspace gas chromatography is a major quality control procedure particularly in the pharmaceutical and food industry. The regulations for this method can be found both in the European as well as the American Pharmacopoeia.
High-boiling solvents of excellent purity, which show no background due to organic volatile impurities on the GC-column, are required for determining solvent residue.
