FromSigma-Aldrich
The ASSET EZ4-NCO sampling device is a unique dry sampler based on derivatization of isocyanate groups with di-n-butylamine (DBA). The sampler consists of a denuder and a filter, both impregnated with DBA. The extract is analyzed using LC-MS or LC-MS-MS offering the ultimate sensitivity and low detection limits not capable with other methods.Most popular related searches
