DX-120型离子色谱仪在水质检测中的应用

Application of Ion Chromatograph in Water Quality Testing

在供水行业中 ,测定水中F-、Cl-、NO3-、SO42 -的方法主要是化学方法 ,其步骤繁多 ,操作复杂费时 ,灵敏度低、干扰大等问题 ,而应用DX - 12 0型离子色谱仪 ,采用浓度淋洗 ,消除干扰 ,从而实现了四种阴离子的同时测定 ,简单 ,快速 (一次分检时间只为 10min)样品用量少 ,检出限低 ,效果令人满意。

In the water supply industry,testing F -,Cl -,NO 3 -,SO 4 2- of water mainly uses chemical method.It exists some problems such as operating complex,taking much more time and steps,lower sensitivity and bigger disturbance etc.But the type DX-120 type ion chromatograph is different.It adopts consistency drip washing and removing chemical disturbances and realizes testing 4 kinds anion at the same time (the testing time approximately 10 minutes once).Operating the method is simple and quickly and save the reagents,the result is very satisfactory.
