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, whichshow 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
