摘要: A flow-injection single-stage dilution module is compared with a dual-stage module. Each stage consists of fixed loop injector, stirred mixing chamber and pulse-free pumping system. The precision both systems rather insensitive to flow rate better than 2% r.s.d. at dispersion coefficients up 106. provides superior performance over large range higher throughput offers much more versatility for sample pretreatment. usually sufficiently powerful inline pretreatment injection analyzers as well other kinds chemical analyzers.
