Description

General description

SupraSolv^® ECD and FID is specially developed for gas chromatography in combination with ECD (Electron Capture Detector) and FID (Flame Ionization detector). 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

Ideal for GC applications including sensitive detection in residue and environmental analysis.
The product is reported for used as a solvent in analyses of:

• commercial technical mixtures (aroclors) and in environmental samples for polychlorinated dibenzo-p-dioxins (PCDD), polychlorinated dibenzofurans (PCDF) and polychlorinated biphenyls (PCB) by high resolution gas chromatography coupled to electron capture detector (HRGC-ECD)
• sewage and soil samples for PCB congeners using HRGC-ECD or HRGC in conjunction with high resolution mass spectrometry (HRMS)

Specifications

Saturation Concentration in Air: 239 g/m3 (20 °C)
