- W2392270517 abstract "Morphine,codeine and 6-acetyl morphine in human blood were detemined via solid-phase extra-ction and gas chromatography/mass spectrometry-selected ion monitoring,with ethyl morphine as internal standard,3 opiates spiked in blank blood were extracted wtih a solid-phase cartridge.The fluent was evapo-rated to dryness followed by being derivatized with MBTFA,and then it was analyzed directly by GC/MS in selected ion mode.The method was validated in a range of 10~1 000 μg/L with the drug-spiked blood,and the reactor responded linearly over the studied range(R20.99 for the 3 drugs).The relative standard deviations(RSD) for intra and inter-days are less than 10% and 16% respectively;the relative extraction recoveries are 90%~116%,90%~110% and 79%~102% sequenfyl for 3 drugs above,and LODs were less than 1,0.5 and 3 μg/L respectively,which promised the perspective application of the method in detecting trace amounts of opium in human blood." @default.
