A short abstract on a method using QuEChERS and GC/MS/MS for determination of fipronil & fipronil sulfone.

Ion-Exchange SPE Methodology

Normal-Phase Methodology in Solid Phase Extraction Microbiology. In order g003572 for polar retention to occur between the sorbent and the sample, the analyte must be introduced to the SPE device in a non-polar sample or mobile phase environment.

HybridSPE-Phospholipid Technology

This Sigma-Aldrich article discusses how the HybridSPE-Phospholipid Technology works and how the phospholipids are removed.

Solid Phase Extraction: Ion Exchange Methodology

SPE retention mechanism in this case is based on the electrostatic attraction of charged functional groups of the analyte(s) to oppositely charged functional groups on the sorbent.
