摘要：

This paper describes a novel calibration method to assay hydrogen cyanide and is based upon the in situ reduction of ethyl thiocyanate (EtSCN) by dithiothreitol to produces HCN which is determined by a headspace GC technique. The method is characterised by good linearity (r = 0.999), good reproducibility (relative SD = 5 %) and a detection limit of 1.5 pmole. An application is described.
