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.


  • Highest purity (mostly ≥99,99 %)
  • High boiling point
  • Non volatile matter: ≤0,001 %
  • Tested for headspace suitability
  • Bottled under protective gas
  • Microfiltered
