Catalog#: 730507 - SPE Cartridges, Chromabond, XTR, 70ml, PP, 14.5g, 30/pk
Detection:
Conditions: Sample aspiration: Pour the liquid onto the kieselguhr column and allow it to absorb for 20 min.
Elution: Extract the kieselguhr with 2 x 40 mL tert-butyl methyl ether.
Evaporation: Combine the eluates in a 100-mL round-bottomed flask and evaporate at 50 °C to approximately 5 mL using a rotary evaporator. Transfer the ether extract to a graduated 10-mL test tube and then carefully reduce to 1 mL under a gentle stream of nitrogen at ambient temperature. Transfer the concentrated extract to a 2-mL vial and crimp.
NOTE 1: It should be avoided evaporating the ether extract to dryness as this has been shown to adversely affect amine recovery.
NOTE 2: The recovery of amines can be improved by converting them to their hydrochloride salts.
