Summary:

Copolymer materials have been used for the collection of vehicle exhaust gas samples since the inception of regulatory standards. Some of these copolymers contain N,N-dimethylacetamide (DMA), which is added to improve the physical properties of the copolymer and eliminate manufacturing problems. DMA is highly soluble in water, and in effect is rinsed from the emission bag surface by humid exhaust gas samples. This study shows that DMA can thus incorrectly add to test vehicle overall hydrocarbon emissions. The DMA contribution can be significant for lower level emission vehicles. This study introduces a new bag material, KYNAR®, which significantly reduces this interference
