Consider the effective dilution factor of your spike (assuming the whole spike passed through the cartridge and was collected with the eluent.) this is equivalent to one of your calibration standards. compare the average spike addition signals for each analyte to the peak areas from the appropriate calibration standard. what % of the added spike was detected? (this is the % recovery through the spe cartridge).
