农产品产地土壤中挥发性有机物

检测方法双柱气相色谱法

1范围

本文件描述了农产品产地土壤中挥发性有机化合物（VOCs）的气相色谱检测方法（双柱气相色

谱法）。

本文件适用于农产品产地及相关土壤中的卤代烃和芳香烃等挥发性有机化合物含量的检测。

2规范性引用文件

下列文件中的内容通过文中的规范性引用而构成本文件必不可少的条款。其中，注日期的引用文

GB/T6682分析实验室用水规格和试验方法

HJ613土壤干物质和水分的测定重量法

NY/T395农田土壤环境质量监测技术规范

NY/T1121.1土壤检测第1部分：土壤样品的采集、处理和贮存

3术语和定义

下列术语和定义适用于本文件。

3.1

农产品产地agriculturalproductionarea

农业活动中获得动物、植物及其生物产品的区域。

4原理

农产品产地土壤中的挥发性有机物由环境的污染及农业投入品的使用而产生，在一定的温度条件

下，顶空瓶内样品中的挥发性有机成分经过挥发，在气、固、液三相达到热力学动态平衡时，用顶空进

样器单针或双针进样，经气相色谱双柱分离，进入氢火焰检测器（FID）和电子捕获检测器（ECD）检

测，分别记录，以保留时间定性，外标或内标定量，计算出目标化合物的含量。

5试剂和材料

5.1试验用水

二次蒸馏水或通过纯水设备制备的水，符合GB/T6682中二级水的要求。使用前应经空白试验，确

认在目标化合物的保留时间区间内，无干扰色谱峰出现或其中的目标化合物浓度低于本方法检出限。
