The water quality of the water source shows a trend of complex pollution, and there is a demand for advanced and strict chlorine treatment and management in water purification processes. The traditional feedback method, which seeks appropriate values after chlorine injection, has posed health and economic issues. Therefore, it is desirable to establish a feed-forward method that captures the chlorine demand of raw water in advance and processes it. From sampling to measurement, all substances in raw water, such as ammonia nitrogen, iron, manganese, and organic matter, will be continuously and fully automatically measured for their chlorine demand in a short time. It can be used as a monitor for surveillance and, in combination with chlorine injection equipment, for accurate chlorine injection control as an automatic proportional injection system. 【Features of the CD-12MF model】 - Improved rotating platinum electrode for residual chlorine detection - No pre-treatment by filtration required even for high turbidity samples - Continuous measurement of chlorine demand in raw water - Follows rapid changes in raw water quality - Expanded screen size for improved visibility - Easy operation via touch panel - Equipped with USB functionality

TOC is an effective tool for cleaning validation of pharmaceuticals, cosmetics, and medical devices. By using TOC for cleaning validation, improvements in quality, risk reduction, and efficient operations can be achieved. TOC is a simple analytical method that rapidly detects low concentrations of organic compounds and can identify degradation products and contaminants that HPLC cannot detect. Compared to HPLC, which is a specific analytical method that detects only specific components, TOC, being a non-specific analytical method, can comprehensively confirm that excipients, degradation products, and cleaning agents are adequately cleaned. Furthermore, TOC simplifies method development and minimizes equipment downtime, leading to increased efficiency. By using TOC, not only can the cleaning process be evaluated quickly, but it also reduces the workload, maintenance costs, and running costs compared to HPLC.
