EPA 552.1 by Strata-X-A on a ZB-XLB-HT

样品制备详细信息

Condition 1 :2 mL Methanol at 1 mL/min
Condition 2 :2 mL Water at 1 mL/min
Load :Load 100.00 mL Sample diluted in Water
Wash 1 :1 mL Methanol at 1 mL/min
Dry :None
Elution 1 :1 mL 10% sulfuric acid in methanol at 1 mL/min
Evaporate: :Evaporate to dryness
Notes : Elute: 1mL of 10% Sulfuric acid in methanol, eluent should be collected in a screw cap vial or test tube to accommodate derivatization. Note: Blank sample extract, post spiked was processed as above to prepare an extracted ref sample (Eref) for absolute recovery calculation Derivatization: Add 2mL of MTBE to the eluent in a screw cap vial or test tube. Heat the sample at 50ºC for 1.5 hours. Remove and allow the sample to cool to room temperature. Slowly add 10mL of saturated sodium bicarbonate and invert the sample several times releasing carbon dioxide gas frequently. Aspirate 100µL of the organic layer and transfer to a 2mL vial with insert. Add 10µL of internal standard (1, 2, 3-Trichloropropane) and inject into GC-ECD system.
