Sigma-Aldrich Supel™ QuE Z-Sep+ enhances sample cleanup for complex matrices by effectively removing more fat and color from sample extracts than traditional phases for QuEChERS LC-MS methods. By eliminating problematic matrix interferences, Z-Sep products provide more robust LC-MS methods. This proprietary technology can replace C18 and PSA in your current methods without additional method development. Z-Sep+ is recommended for cleanup of samples containing greater than 15% fat.
