Application #: 303720
Catalog#: 730507 - SPE Cartridges, Chromabond, XTR, 70ml, PP, 14.5g, 30/pk
Detection: If necessary the extract was diluted appropriately with the HPLC mobile phase before filtrated through a 0.45 µm membrane filter. 40 µL were injected into a HPLC system. Please see HPLC application 11
Conditions: Sample aspiration: 20 mL of the saponified sample solution were poured onto the Chromabond cartridge and allowed to absorb for 15 min.
Column washing: No washing was proceeded.
Elution: The vitamins were eluted, using 100 mL of n-hexane (containing 5 mg BHT; 2,6-di-tert-butyl-p-cresol).
