Analysis of Total Nitrosamines
Oct 22 2014
In certain production processes such as those in cosmetics or agricultural pesticides industries, it is important to analyse for the presence of Nitrosamines, but it is not all ways essential to know the exact profile of the nitrosamine species.
The Ellutia Chemical Stripping System has been developed to be used in unison with an 800 Series TEA to perform total nitrosamine analysis. Instead of using a pyrolyser to heat the nitrosamine to remove the NO group, a chemical reaction can be employed. The alleviation of NO from the nitrosamine is performed by a reflux reaction with hydrobromic acid in ethyl acetate. The nitrosamine sample is injected into the reaction vessel and produces NO, a secondary amine and bromine. The NO is then carried in a gas stream through a cold trap (removing any vapour) to the TEA
