High accuracy and dependability for detecting low levels of TOC
Changes in water quality for ultra pure applications are disruptive to plant operations. Accurate, on-line analyzis is important to protect critical equipment that depends on ultra pure water resources. Leading manufacturers know that it is critical to analyze for contaminates precisely at ppb levels to maintain water quality. Reliability and effective oxidation of large samples ensures that manufacturers can trust the results reported by the BioTector B3500ul analyzer. With a full picture of organic contaminants in critical water applications manufacturers make water treatment decisions more efficiently.
The Hach BioTector B3500ul provides reliable and accurate TOC analyzis at ppb levels for ultrapure water applications. The patented two stage advanced oxidation technology behind the BioTector thoroughly, and reliably oxidises samples for valuable real-time water analyzis.
The Hach BioTector B3500ul analyzer can be configured as:
1. A TIC & TOC (NPOC) system to measure the Total Inorganic Carbon (TIC) and Total Organic Carbon (TOC) content of a liquid sample. The TOC result obtained from a TIC & TOC system represents the Non-Purgeable Organic Carbon (NPOC) because VOC (POC) compounds may partly escape from the sample during TIC stripping. The TIC & TOC system is suitable for samples that contain very low or insignificant concentrations of volatile organic materials.
2. A TC system to measure the Total Carbon (TC) content of a sample. The TC result obtained from a TC system represents the sum of TIC, NPOC and VOC content.
3. A VOC system to measure the TIC, TOC, TC and VOC contents of a sample. The TOC result in a VOC system is calculated from the TC and TIC measurements as TOC = TC – TIC. Therefore, the TOC result includes the volatiles present in the sample. In other words, the TOC result represents the sum of NPOC and VOC (POC) content.
