The combination of an ultra-short C18 monolithic column (5 mm long) with a flow injection analysis (FIA) scheme results in a versatile and efficient system that has been used for the chromatographic determination of four preservatives — methylparab

A spectrophotometric method for the simultaneous determination of sulphathiazole and sulphametazine based on fourth-derivative solid-phase spectrophotometry is proposed. Both sulphonamides were fixed on a dextran-type cation-exchange gel at pH 2.5. T

Sulphathiazole in the presence of sulphametazine is determined by a method based on derivative solid-phase spectrophotometry. Both compounds are fixed on a dextran-type cation-exchange gel. The absorbance of the gel, packed in a 1-mm silica cell, is
