821 Results for: "GC SOLVENTS"

Solid supported liquid/liquid extraction (SLE) is a fast effective sample preparation technique that provides considerable benefits over liquid-liquid extraction (LLE) protcols for removal of phospholipids, from biological samples. HyperSep™ SLE deals with sample preparation of biological matricies via a simple, efficient and an effective protocol, the focus being the removal of interfering phospholipids which cause a number of issues for end point analysis.

Cyclohexane ≥99.8%, SupraSolv® for GC-MS, distilled, Supelco®

Supplier: MilliporeSigma

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 minimal signal-to-noise ratio leading to reliable and reproducible analysis results. This method is used e. g. for the analysis of dioxins and furans (PCDD/PCDF) in food and water samples or for the determination of PAH (polycyclic aromatic hydrocarbons) in food.
