3 Terms and Definitions
Terms and definitions GB/T 21863-2008 defined in 3.1 are applicable to this document.
4 principle of the method
Gel permeation chromatography is the use of polymer molecules through the porous filler is filled with a special column, the column according to the molecular scale
Inch size separation, molecular volume (molecular weight) to a large outflow small due to the long residence time in the column effluent and then, the effluent
After detection, and automatic recording parameters such as molecular weight and molecular weight distribution of the sample to obtain a GPC chromatogram. The root of this spectrum
According to the standard curve using standard polystyrene samples of known molecular weights obtained, calculated relative molecular weight and molecular weight distribution of the sample
And other data.
5 Sampling
Sampling methods to perform according to the provisions GB/T 6679 and GB/T 3723's.
6 Reagents
Former tetrahydrofuran, HPLC grade, need to use degassed.
Benzene, AR.
Narrow distribution polystyrene standards, distribution coefficient D≤1.10.
