Fast Extraction and Low Level Detection of Chloramphenicol in Shrimp

19 Oct 2014

In this application note, several different QuEChERS sorbents were used in the sample cleanup procedure of shrimp samples prior to chloramphenicol analysis. Analyte recovery, reproducibility and ionization effects were compared.

Supel™ QuE Z-Sep QuEChERS Tubes

Sigma-Aldrich Supelco

Supel QuE Z-Sep sorbents enhance sample cleanup for complex matrices by effectively removing more fat and color from sample extracts than traditional phases for QuEChERS. By eliminating problematic matrix interferences, Z-Sep products provide more robust LC-MS and GC-MS methods. This proprietary technology can replace C18 and PSA phases in your current methods without additional method development.Supel QuE Z-Sep/C18, a combination of Discovery® DSC-18 and Z-Sep particles, is recommended for samples containing <15% fat. Supel QuE Z-Sep+, C18 and Z-Sep dual bonded to silica, is recommended for cleanup of samples containing >15% fat. Supel QuE Z-Sep is recommended for the anlysis of hydrophobic analytes in fatty matrices.Features & Benefits: Useful for pesticide residue analysis Proprietary technology, significantly diminishes interference from fatty matrices and pigments Employs “Quick Easy Cheap Effective Rugged Safe” QuEChERS methodology
