GC analysis of coarse caprolactam and existed approximately 10% of impurities.In the identification of especially big impurities peak number 4 point aiming, high-resolution GC-MS measurement.
The crude caprolactam to GC analysis, was present impurities is about 10%. Of these, especially in order to identify a large impurity peak number 4 points and subjected to high resolution GC-MS measurement.
GC crude caprolactam and analysis to the present is about 10%. At the four points to the identification of a large number of impurity peak, high resolution and GC MS measurement. At
