Supel™ QuE Z-Sep QuEChERS Tubes
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 combi…

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
Fast Extraction and Low Level Detection of Chloramphenicol in Shrimp
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.
Intra-Laboratory Validation of an Alternative Column Chemistry for the LC-MS/MS Analysis of Pesticides in Fruits and Vegetables Using Method EN 15662
LC-MS/MS methods are very popular for the analysis of pesticides in food. Several methods currently exist for their extraction from a variety of different food matrices. One of the newer methods is known as the QuEChERS, this method employs dispersive solid phase extraction (SPE) for extraction and cleanup. This method is now the European Norm (EN 15662). While this method typically uses C18 HPLC columns, this application note describes an intra-laboratory comparison and validation procedure using an Ascentis® Express RP-Amide column.
Improved Recovery of the Fungicide Carbendazim from Various Orange Juice Matrices by Employing QuEChERS Cleanup
In this application note a single method, involving fast and effective QuEChERS cleanup, suitable for various orange juice matrices is presented. The choice of PSA/C18 sorbents reduced interferences, resulting in greater recoveries and less ion-suppression. Sample processing using QuEChERS with PSA/C18 allows analysts to accurately process various matrices in a single workflow, with very little additional sample preparation time.
Increased Removal of Fat and Pigment from Avocado Extracts Prior to GC-MS Analysis of Pesticide and Metabolite Residues
This work compares the effectiveness of two sorbents, Z-Sep+ and a PSA/C18 blend, in the QuEChERS cleanup of avocado extracts prior to pesticide residue analysis by GC-MS.
