Abstract
In order to obtain fundamental informations on the application of electron capture gas chromatography to the acaricides, retention times and peak area sensitivities were investigated on the four operating conditions containing 2% PEGA, 5% DC-11, 2% QF-1 and 10% SE-30.
Retention times of CPAS, azoxybenzene and FABB was short, and those of tetradifon and bromopropylate was long. Peak area sensitivity of quinoxaline derivatives and organic chlorine compounds involving sulfur was higher than organic chlorine compounds without sulfur. By the ccmbination of four operating conditions, mixture of 20 acaricides could be mutually separated. The linear ranges of calibration curves of kelthane, for example, was 0.540ng.
