title: Simultaneous determination of neopynamine and piperonyl butoxide by capillary column gas-liquid chromatography.
abstract: A method is developed for the simultaneous determination of neopynamine and piperonyl butoxide by chromatography on a quartz capillary column using flame ionization detection. Benzyl mandelate is used as an internal standard. Calibration graphs are linear down to at least 3.75 mg% and 3 mg% for neopynamine and piperonyl butoxide, respectively.
