On-Line TOC Analyzer for Pure Water
Online Measurement of Ultra-pure Water Using TOC-1000e
When used in the pharmaceutical and semiconductor industries, it is important to continuously control the quality of pure water to keep the impurities at low level. For optimum quality control of ultra-pure water, the online total organic carbon analyzer TOC-1000e enables highly sensitive analysis with a lower detection limit as low as 0.1 µg/L based on the UV oxidation-conductivity measurement method. This article introduces an example of online measurement of ultra-pure water using TOC-1000e.
TOC System Suitability Test Using TOC-1000e According to USP 643
For water used in pharmaceuticals, the US Pharmacopoeia (USP) specifies that total organic carbon (TOC) should be used for management of organic impurities. According to USP 643 TOC, TOC analyzers to be used for analysis of bulk purified water and water for injection must satisfy the TOC system suitability test using test water with a carbon content of 0.500 mg/L. This article introduces an actual example of TOC system suitability testing using the online total organic carbon analyzer TOC-1000e and optional sampler.
