After centrifugation, the extracts were separated on HILIC column by using acetonitrile-water as mobile phase. The analytes were identified and quantitated by LC-tandem MS under the positive/negative electrospray ionization and multiple reaction monitormode. The calibration curves showed good linearity in the range of 25-5000 μg/kg for melamine and cyanuric acid, and 50-10000 μg/kg for ammeline and ammelide. The limits of detection and limits of quantification were in the range of 5-20 μg/kg and 50-100 μg/kg, respectively.

The results showed that there was a more better effect of filmformation and absorbency to use poly 1788 as an adhesive and polyvinyl pyrrolidone(K:90) as a hydrophilic polymer. The silicon dioxide with particle size 0.3-1 μm as a inorganic pigment had a better absorbency. The polyethylene glycol modified with ethylenediamine had a more better characteristic of dye immobilization, absorbency and definition than the polyethylene glycol modified with diethylenetriamine, of which the polyethylene glycol of molecular weight of 400 modifiedwith ethylenediamine had more best performance.

研究结果表明：采用聚乙烯醇1788作黏合剂、聚乙烯吡咯烷酮(K值为90)作亲水性高分子可得到比较理想的成膜效果和吸墨效果；粒径分布范围在0.3-1 μm的二氧化硅作为无机颜料具有较好的吸墨性能；用乙二胺改性的聚乙二醇比用二乙三胺改性的聚乙二醇具有更好的固墨性、吸墨效果以及清晰度，其中乙二胺改性的分子量为400的聚乙二醇所得到的烷基多胺的效果为最好。
