Description

General description

SupraSolv^® MS is dedicated for use in gas chromatography coupled with mass spectrometric detection. SupraSolv^® solvents offer the largest specified retention time range, a clear baseline and a minimum signal-to-noise ratio leading to reliable and reproducible analysis results.

Application

Used for extraction and GC analysis using MS detection.
Also used for the analyses of:

• polychlorinated dibenzodioxins and polychlorinated dibenzofurans (PCDD/F) in food and water samples
• polycyclic aromatic hydrocarbons (PAHs) in food

Packaging

1 , 2.5 , 1 l

Analysis Note

Evaporation Number: 1.9
