The ideal on-line TOC Analyzer to achieve precise results even for your most challenging applications
Hach BioTector TOC analyzers are engineered to help operators address the toughest water quality challenges. Many plants struggle with high maintenance and downtime caused by sample contamination from salts, particulates, fats, oils, and greases. Conventional TOC analyzers often cannot keep up, leading to drifting results and costly interventions.
BioTector analyzers solve these problems with patented self-cleaning, two-stage advanced oxidation technology, designed to handle even challenging applications involving sludge, greases, salts, and particulates—without the need for filtration. Oversized tubing prevents blockages and lowers the risk of sample contamination. With minimal maintenance required and no calibration or operator intervention between service intervals, you can count on maximum uptime and reliable performance. Continuous monitoring and real-time control enable process optimization and help reduce overall operating costs.
Configurable to fit application needs, BioTector analyzers offer:
1. TIC & TOC (NPOC) System: Measures Total Inorganic Carbon (TIC) and Total Organic Carbon (TOC) content in liquid samples for accurate NPOC determination.
2. TC System: Measures Total Carbon (TC), representing the sum of TIC, NPOC, and VOC content.
3. VOC System: Measures TIC, TOC, TC, and VOC contents. The TOC result equals the combined NPOC and volatile organic carbon (POC) content.
BioTector’s robust design delivers precise results for a wide range of applications, from simple to demanding, and supports fast payback from savings in chemical dosing, waste management, and process efficiency.
