UHT产品三聚氰胺检测方法中前处理改进方法

UHT products melamine testing method of pretreatment improvement Detection method

研究TUHT产品三聚氰胺检测过程中前处理的检测方法，样品前处理利用透析纸或透析袋的热熔性和透析度，通过分子隔断筛选，使三聚氰胺分子自由穿入并溶于水中。此方法与国标方法比较：透析方法的前处理省时省事，并且所用消耗品较少，总体成本较现用方法便宜，但是在使用透析纸密封样品时必须小心包扎，不能漏样。

Study the UHT products melamine testing process of pretreatment detection method, sample preparation using dialysis paper or dialysis bag of hot melt and dialysis degrees, through the molecular partition screening, that melamine molecular free inserted and soluble in water. This method and national standard method is： dialysis methods of pretreatment time save trouble, and consumables used less, overall cost is active method cheap, but in the use of dialysis paper sealed sample must be wrapping up, can＇ t leak sample.
