GB 5750 | 睿科聚集环境水质，无忧水体异味物质检测

版块：机械制造类型：普通作者：化工产业技术分享查看：74 回复：0 获赞：0 时间：2022-05-18 18:34:02

近年来，水体嗅味问题普遍存在，其主要原因是土臭素（Geosmin，GSM）和2-甲基异崁醇（2-methylisoborneol，MIB或2-MIB）两种藻类分泌物的存在。我国大多数饮用水为地下水，存在土臭素和2-甲基异崁醇的几率十分高，因而对水体中这些物质含量进行测定极为重要。固相微萃取技能是集采样、萃取、浓缩、进样于一体，克服了传统萃取办法的缺陷，样品用量少、操作简略、便利、省时省力、运用溶剂少或不运用溶剂。

睿科集团针对GB 5749《日子饮用水卫生规范》征求意见稿和GB/T 5750《日子饮用水规范查验办法》征求意见稿-水质异味物质检测，具有一系列解决方案，满意客户不同样品前处理的需求。

使用事例：水中土臭素和2-甲基异莰醇的测定

前处理-新拓固相微萃取（SPME）

气质联用检测条件
