水源水中乙醛、丙xi醛卫生检验标准方法20%聚乙二醇-20M/6201填充柱

水源水中乙醛、丙xi醛卫生检验标准方法20%聚乙二醇-20M/6201填充柱 详细信息:


名称:螺旋形不锈钢柱
固定相:以20%聚乙二醇20M为固定液,涂渍在 6201釉化担体(60^80目)上
规格:2m*4mm(内径)

应用:GB 11934-1989 水源水中乙醛、丙xi醛卫生检验标准方法 气相色谱法


本标准规定了用气相色谱法测定水源水中的乙醛、丙xi醛。
本标准适用于测定水源水中乙醛、丙xi醛。如直接进样,本法zui低检测浓度乙醛为。.24m g/L,丙xi醛为0.019 mg/L。若进行蒸馏浓缩,zui低检测浓度还可降低。
注: 依据国jia标准quan文公开系统,该标准已调整为推荐性。

Standard method for hygienic inspection of acetaldehyde and propionaldehyde in water source water 20% polyethylene glycol-20M/6201 packed column


Standard method for hygienic inspection of acetaldehyde and propionaldehyde in water source water 20% polyethylene glycol-20M/6201 packed column Details:




Name: Spiral stainless steel column

Stationary phase: use 20% polyethylene glycol 20M as the stationary liquid, and coat it on the 6201 glazed support (60^80 mesh)

Specification: 2m*4mm (inner diameter)

Application: GB 11934-1989 Standard method for hygienic inspection of acetaldehyde and propionaldehyde in source water gas chromatography




This standard specifies the use of gas chromatography to determine acetaldehyde and propionaldehyde in source water.

This standard applies to the determination of acetaldehyde and propionaldehyde in water source water. Such as direct injection, this method has the lowest detection concentration of acetaldehyde. .24mg/L, propionyl aldehyde is 0.019 mg/L. If distilled and concentrated, the lowest detection concentration can be reduced.

Note: According to the national standard full-text disclosure system, this standard has been adjusted to be recommended.
