GCHS Promo

New GC-Headspace grade

High purity solvents for accurate and reliable analysis of organic volatile impurities (OVIs) by gas chromatography headspace (GC-HS)

The determination of residual solvents (organic volatile impurities) by GC headspace is an important quality control procedure in the pharmaceutical industry.

The technique requires extraction of residual solvents from the sample using a high purity solvent free of contaminants that could interfere with GC analysis by co-eluting with the peaks of interest. ICH guidelines include maximum concentration limits for class1,class2 & class3 residual solvents (most to least toxic,respectively)

Fisher Chemicals GC Headspace solvents are performance tested to ensure absence of trace level ICH residual solvents.

Key Features:

  • Processed to high purity for accurate and repeatable determination of trace levels of Class 1, Class 2, and Class 3 residual solvents in pharmaceuticals
  • Tested by UV absorbance to ensure low organic contamination
  • Processed for low water content to facilitate the extraction of organic volatile impurities
  • Packaged in an inert atmosphere to maximize shelf life in unopened containers

* Offer Valid for below GC Headspace products:

D133-1 N,N-Dimethylformamide, 99.9+%, GC Headspace
D160-1 N,N-Dimethylacetamide, GC Headspace
D139-1 Dimethyl sulfoxide, GC headspace
