||Description of a liquid chromatography method (high performance) which overcomes some of the disadvantages of spectrophotometric methods (high separation sensitivity for isocyanate adducts). The air to be analysed is passed through a solution of 9-(N-methylaminomethyl)anthracene in toluene. Reaction times vary between 20min and 2h according to the type of isocyanate. The sample is eluted with an acetonitrile/triethylammonium phosphate buffer solution. Detection is by measuring UV absorbance (254nm).
