Abstract
An improved zone sampling method where a small volume mixing device is placed before the fraction loop has been developed. In this method the samples are dispersed by the gradient chamber (device) and its dispersion profile of the injected samples is exponential. Therefore, the fraction difference caused by a lug of the fraction timing is small and consequently the optimization of system is very easy. The method was applied to the predilution of the samples in clinical flow injection analysis.
