| Abstract: | The quantitative analysis of N,N-dimethylformamide was determined by GC with 3% polyethylene glycol 20000/Chromosorb W AW DMCS (40 to 60 μm) glass column, and by using n-pentanol as internal standard. Separation was conducted at a input port temperature of 230℃, a detector temperature of 230℃, a column temperature of 200℃, and a carrier gas (nitrogen) flow rate of 40 mL/min using FID detector to quantitative analysis N,N-dimethylformamide. The standard deviation was 0.04, variation coefficient was 1.26%, average recovery was 99.57%, liner correlation was 0.999 9. |
