| Resumen |
This high-pressure liquid chromatography method has been developped to meet the requirements of the "common control limit" for workplace exposure to all isocyantes recently promulgated in the United Kingdom (20µg NCO/m3 for an 8h TWA). It has been modified to measure both the monomer and prepolymer. A dual detection system (electrochemical and UV) is used to identify the isocyanate derivatives and quantify them by reference to a monomer standard. The precision of the method is >10% over the range 35 to 140µg(NCO)/m3 for a 10min sample. Accuracy is ±19%. |
