Popis

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.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Heptane is an environmentally preferable solvent compared to hexane and thus align with "Safer Solvents and Auxiliaries". Click here for more information.

Application

Appropriate for GC applications including sensitive detection in residue and environmental analysis.
