Simultaneous Quantitative Determination of Seven Isothiocyanates by Gas Chromatography Equipped with FPD

Abstract

Using the technique of gas chromatography equipped with FPD, concentrations of 7 isothiocyanates, iso-propyl isothiocyanate (itc), sec-butyl itc, n-butyl itc, allyl itc, 3-butenyl itc, 3-methylthiopropyl itc and β-phenethyl itc, were determined. In these cases, the formulas, y=ax^b, were established in each case. Where x are concentrations of these isothiocyanates, y are [peak areas of these isothiocyanates/that of internal standard (phenyl isothiocyanate)]x100, a and b are constant number. Therefore, simultaneous determination of 7 isothiocyanates in natural material hydrolysate became to capable.
