Resolution of an intense sweetener mixture by use of a flow injection sensor with on-line solid-phase extraction

Abstract  An integrated solid-phase spectrophotometry–FIA method is proposed for simultaneous determination of the mixture of saccharin (1,2-benzisothiazol-3(2H)-one-1,1-dioxide; E-954) (SA) and aspartame (N-l-α-aspartyl-l-phe
