REFERENCE STANDARDS FOR GAS CHROMATOGRAPHY

Residual solvents, commonly referred to volatile impurities, are trace organic solvents
that may be found after the production process of many products used in our daily life,
such as, active substances and excipients in pharmaceutical medications, cosmetic
ingredients and various food products. Their identification and quantification are
therefore an essential part of the content specifications and safety of such products.
A common technique for the chemical analyses of residual solvents relates to Gas
Chromatography (GC) for which highly pure GC standards are needed.

Biosolve offers a broad range of highly pure GC reference standards for various GC
applications. The majority of our GC reference standards are completely synthetic and
typically over 99.9% pure. The purity and the specific impurity profile of each standard is
determined by GC-FID and GC-MS and reported in the certificate of analysis of each
manufactured lot. Assay is determined against traceable, certified international
standards.

Partial list of available GC reference standards:

Product Cat. No.
Acetic acid 010772
Acetone 010372
Acetonitrile 012072
Ethanol 052572
n-Hexane 99%+ 080972
Methanol 136872
2-Propanol 162672
Tetrahydrofuran 202272
Toluene 201572

Biosolve GC reference standards are commonly bottled in 10ml and 100ml packages. For more reference
