✦ Synopsis

The potential of a flow-mJechon-zone samphng system equtpped with a dmde-array spectrophotometnc detector for the simultaneous determmatlon of metal 1011s 111 mrxtures was studled Zone samplmg was accomphshed by usmg a uxnmerc~ally avadable, vanable-volume, dual-channel bypass mJectlon valve The mixed spectra were recorded at the maxlmum of the flow-mjectlon peaks and were resolved mto the mdwldual components by using a partial least-squares method The method was apphed to the detemunatlons of Cu(I1) and Z&I) m murtures with 4-(2-pyr~dylazo)resorcmol as reagent
