DMAC Analysis (N,N-Dimethylacetamide)
Testing to identify and determine levels of N,N-Dimethylacetamide (DMAC)
Impact Analytical has developed a method to quantify residual N,N-Dimethylacetamide (DMAC) in various polymer and polyimide film samples. The European Union has recently proposed adding DMAC to the current REACH list of SVHC (Substances of Very High Concern). In a proactive measure, some companies are adding DMAC to their restricted and prohibited list.
DMAC is commonly used as a solvent in the manufacture of fibers and is also used in the production of films, pharmaceuticals and plasticizers as a reaction medium. Thus, there is typically a small amount of DMAC as a residual solvent left in these products. Our analysis for DMAC will tell customers how much of the compound remains in their final product.
A method for residual DMAC testing has been developed using gas chromatography mass spectrometry (GC-MS) that successfully identifies and quantitates levels of DMAC in the low part-per-million (ppm) level.
DMAC analysis can be performed on many samples including:
