After separation,we got the result by GC-8900 gas phase color spectrometer .

文中对待分离的混合液，经分离后，用GC8900气相色谱仪对固相，液相分别测定了他们的含量。

At present inland the shortcoming in separation is that the resolution and use ratio of resin is low, the amount of coloring matter contained in products is too high, and the purity and yield of nucleotides is too low and etc.

目前国内在分离方面存在的缺点是：所用树脂的分离度低；树脂利用率低；所得产品色素含量高；产品的收率和纯度较低等。
