The two methods US EPA 5B/202 (Wet Method) and US EPA 51/202 both showed good agreement in the total condensables levels, However, in general, the wet method showed increment in the inorganic portion compared to the dry method. This could partially due to the gaseous contaminants (such ...
This disposability avoids contamination from one sample to the next, which is invaluable for tests performed subject to, for and/or by regulatory agencies like the EPA and FDA where contamination is a concern. In one embodiment of the present invention, a planar MEMS FAIMS chip was fabricated i...
