Karl Fischer Aqualine Promotion

Karl Fischer titration is the most widely used analytical technique for determination of water content in the pharmaceutical industry.

Water plays a critical role in physical and chemical stability of active pharmaceutical ingredient (API) and drug product.

Pharmacopeia allows the use of commercially available Karl Fischer reagents.

As per USP <921> Water determination: “For determination of trace amounts of water (less than 1%), it is preferable to use a Reagent with a water equivalency factor of not more than 2.0”

Fisher Chemicals offers Aqualine Karl Fischer reagents designed to meet this exact need of the analytical chemist.

K/1900/15 Aqualine® Complete 1, for Karl Fischer analysis Water equivalent 1mg H2O/ml
K/1950/15 Aqualine® Complete 2, for Karl Fischer analysis Water equivalent 2mg H2O/ml

In addition we also provide,

K/2000/15 Aqualine® Complete 5, for Karl Fischer analysis Water equivalent 5mg H2O/ml

Rigorous quality assurance and testing procedures throughout the production process ensure the lot-to-lot consistency required for reproducible results

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
N140-1 1-Methyl-2-pyrrolidone, GC headspace
