GC-ECD as a method of detection for nitrosamines

Was anybody at Pittcon?

I have seen one article mentioning that a presentation was given there about the use of GC-ECD for the testing of nitrosamines, especially for halogenated nitrosamines, to a level of 20 ppb. While this may or may not be sensitive enough, depending on the nitrosamine, daily dose and permitted levels, it is a novel detection method to me in this issue.
