TOC-VWP

Wet Oxidation TOC Analyzer

 toc-vwp

新设计的高灵敏度NDIR能实现高灵敏度测量。将阻碍准确分析的试剂空白更小化，提高灵敏度和准确性。通过结合过硫酸盐，紫外线照射和加热实现氧化。无需清洗试剂瓶，减少载体气体消耗。

测量原理

TC测量

将磷酸与氧化剂（硫酸铵）添加到样品中，在紫外线照射下加热，将样品中的TC转换成二氧化碳。二氧化碳与载气通过除湿机流入NDIR抽样单元。测量二氧化碳峰值信号的范围，使用预先准备好的校准曲线将峰值面积转换为TC浓度。

IC测量

使用磷酸将样品酸化和吹扫，将样品中的IC转换成二氧化碳。通过NDIR检测二氧化碳，样品的IC浓度测量方法与TC相同。

TOC测定

从TC浓度中减去IC浓度得出TOC的浓度。

NPOC测定

使用磷酸将样品酸化，旋转去除IC。该NPOC浓度是在去除IC后通过测量样品中的TC（=npoc）得出的，测量方法与TC相同。
