[GC study of N,N-DMAC in medical polyurethane fiber membrane]

Medical polyurethane fiber membrane after extraction with water, and then establish the determination of N, N dimethyl acetamide (DMAC) in Medical polyurethane fiber membrane by GC, and discuss the analysis and evaluation of other extracts of polyurethane fiber membrane for the determination of DMAC in the linear range of the average recovery rate was more than 90%, the RSD 1.51%-2.08% (n = 6). This method is simple, fast, sensitive and accurate, and may serve as a mass control method for DMAC in Medical polyurethane fiber membrane.
