This paper describes a method for the simple and rapid detection of methamphetamine and amphetamine simultaneously in urine, based on gas chromatography with a solid-phase micro-extraction technique.
Abstract
The research used an SPME filter with a fiber holder for manual use. After the addition of urine, NaCl, and 1-phenylbutylamine, the sample was adjusted to pH12 with NaOH(10N) and then rapidly sealed with a teflon-coated septum. After immersion of the SPME fiber in the sample for 20 minutes and then washing promptly in a bugger, the SPME needle was inserted into the injection port of the gas chromatographer and the fiber was extruded. Each peal of methamphetamine, amphetamine, and 1-phenylbutylamine was clearly separated. The linearity of the amphetamine and methamphetamine were in the ranges of 0.25-10 and 0.1-1.0 micrograms per milliliter, respectively. This SPME technique is applicable without using organic solvents, as well as simple, rapid, and useful for the practical detection of methamphetamine and amphetamine in urine.
