TOC-2000D型多功能碳含量测定仪的设计

Design of a multifunctional carbon content measuring instrument

介绍了TOC-2000D型多功能碳含量测定仪的工作原理及部分关键部件的改进与创新设计。该仪器主要用于水体中总有机碳(TOC)指标的测定,亦可用于水体中总碳(TC)、总无机碳(TIC)、溶解态有机碳(DOC)、颗粒态有机碳(POC)、可挥发性有机碳(VOC)的测定,此外还可用于工业废渣、土壤、淤泥中固态有机碳(SOC)含量的测定。仪器测量范围为0～50mg/L、0～500mg/L、0～5000mg/L(可任选),重复性≤2.6%,直线性≤2.7%,量程漂移性≤1.4%,响应时间≤3min。

The working principle and the improvement and novel design of several key parts of a multifunctional carbon content measuring instrument are described. The instrument is mainly used for measuring total organic carbon （TOC） index in water, but it can also be used for measuring total carbon （TC）, total inorganic carbon （TIC）, dissolved organic carbon （DOC）, particulate organic carbon （POC） and volatile organic carbon in water, and for measuring solid organic carbon （SOD） in industrial waste residue, soil and silt. The measurement ranges are 0～50mg/L, 0～500mg/L and 0～5000mg/L （for option）. Other specifications of the instrument are ： reproducibility≤2.6 %, linearity≤2.7%, drift of measurement range 41.4% , response time≤3min.
