随着水环境污染的日愈严重，人们对饮用水安全意识也在不断增加，2001年卫生部《生活饮用水卫生规范》中规定了水中苯系物测定方法，其中法为二硫化碳萃取填充柱气相色谱法。

苯系物是环境中常见的有机污染物，毒性很大，有“三致”（致癌、致畸、致突变）危害，是我国环境监测中优先控制污染物。水中苯系物的测定主要采用气相色谱法，苯系物在饮用水或地表水中的浓度一般较低，在痕量分析之前需要对样品进行预处理。水中苯系物测定方法中预处理方法主要有二硫化碳萃取法和静态项空法。二硫化碳在氢火焰上信号响应小，在填充柱上能和目标物较好的分离。

滕州市浩瀚色谱仪器技术服务有限公司，指出了气相色谱法测定水质苯系物存在的不足。提出用 3%有机皂土 - 34+2 .5 %邻苯二甲酸二壬酯混合涂渍的 Chromosorb G.DMCS 担体 (8 0目～ 100目 )不锈钢色谱柱分离苯系物 ,可在 12min内分离水样中 7种苯系物 ,对二甲苯与间二甲苯等难分离物质对可完全分离。改进后的样品前处理顶空装置操作简单、安全 ,可连续自动振荡 ,并且可以同时处理多个样品.


此柱柱效高，3种异构体临/间/对-二甲苯分离彻底，分析时间适中，避免了2.5米/3米/3.5米/4米填充柱分析时间冗长，柱效低，效率低下的缺陷。

浩瀚色谱生产的每根色谱柱都经过严格的测试评价，出厂采用的铝膜密封袋包装，精致，大气，上档次。

As the pollution of the water environment becomes more and more serious, people's awareness of drinking water safety is also increasing. In 2001, the Ministry of Health's "Drinking Water Hygiene Code" stipulated the determination method of benzene series in water. The first method is carbon disulfide extraction and filling. Column gas chromatography.

Benzene is a common organic pollutant in the environment. It is very toxic and has "three causes" (carcinogenic, teratogenic, and mutagenic) hazards. It is the priority control pollutant in my country's environmental monitoring. The determination of benzene series in water mainly adopts gas chromatography. The concentration of benzene series in drinking water or surface water is generally low, and samples need to be pretreated before trace analysis. The pretreatment methods in the determination of benzene series in water mainly include carbon disulfide extraction method and static term empty method. Carbon disulfide has a small signal response on hydrogen flame and can be separated from the target better on the packed column.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. pointed out the deficiencies in the determination of benzene series in water by gas chromatography. It is proposed to use 3% organic bentonite-34+2.5% dinonyl phthalate mixed coated Chromosorb G.DMCS support (80 mesh to 100 mesh) stainless steel chromatographic column to separate benzene series, which can be within 12 minutes Separate 7 kinds of benzene series in the water sample, para-xylene and meta-xylene and other difficult-to-separate substances can be completely separated. The improved sample pretreatment headspace device is simple and safe to operate, can continuously and automatically oscillate, and can process multiple samples at the same time.


This column has high column efficiency, complete separation of 3 isomers, pre/inter/para-xylene, moderate analysis time, avoiding the lengthy analysis time of 2.5m/3m/3.5m/4m packed column, low column efficiency and efficiency Low defect.

Each chromatographic column produced by Haohan Chromatography has undergone rigorous testing and evaluation. It is packaged in high-end aluminum film sealed bags, exquisite, atmospheric and high-grade.
