A method for determination of thiocyanate by gas-phase molecular absorption spectrometry is described. The proposed method is based on the continuous generation of carbonyl sulphide and preconcentration in a liquid nitrogen trap. Later, the product is volatilised and the absorbance at 224 nm is meas
