title: Separation of standard opiates and their analysis in pharmaceutical and illicit preparations by paired-ion reverse-phase high-pressure liquid chromatography.
abstract: The separation of standard opiates in a mixture and their analysis in clandestine and pharmaceutical preparations were accomplished by PIC on a micro-Bondapak C18 column. The identification of the opiates was based on two parameters: retention times and the ratios of absorbance peaks recorded at 254 and 280 nm. No prior clean-up procedure of samples was required for analysis by this method. Baseline separation of drug components in clandestine and in pharmaceutical preparations made this method suitable for their quantitation.
