Automated solid-phase extraction of opiates from urine (II). Establishing criteria for the detection of opiate abuse.
Automation in the laboratory was taken one step further with the introduction of automated solid-phase extraction of opiates from urine using C18 bonded-phase columns as an alternative to traditional liquid-liquid partitioning. A comparison of the automated procedure with an established liquid-liquid extraction procedure showed a linear correlation between the two over the concentration range studied. Criteria for the identification of opiate abusers were established to adapt this new methodology to large-scale screening of urine specimens.
