What is TOC?  

TOC Analysis – Dirty Glass Water – Hach

TOC or Total Organic Carbon detection is an important measurement because of the effects it may have on the environment, human health, and manufacturing processes. TOC is a highly sensitive, non-specific measurement of all organics present in a sample. It can be used to regulate the organic chemical discharge to the environment in a manufacturing plant. In addition, low TOC can confirm the absence of potentially harmful organic chemicals in water used to manufacture pharmaceutical products. TOC is also of interest in the field of potable water purification due to disinfection of byproducts. Inorganic carbon poses little to no threat.

Hach's Biotector TOC Analyzer can be used for multiple industrial and special applications. For ultrapure and pharmaceutical applictions please see Anatel TOC. 

Product Spotlight  

Hach BioTector Online TOC/TN Analyzer, Plus Model

B7000 - Maximum Uptime and Reliability: Any Application, Any Condition
Hach BioTector B7000 TOC Analyzers use a patented self-cleaning oxidation technology (TSAO) to easily handle difficult samples and significantly reduce the maintenance schedule and costs associated with traditional on-line measurement.

B3500c - Maximum Uptime and Reliability: Clean Water Applications
Using patented technology, only requiring scheduled maintenance every 6 months, allowing for dual stream monitoring, and having one of the most compact analyzer footprints, the Hach BioTector B3500c delivers 99.8% uptime in condensate applications with the lowest operating cost.

Technology Comparison  


  TSAO (BioTector) Thermal UV Persulfate
Calcium and salt Causes no impact with chlorides up to 30% and calcium up to 12%. Leads to analyzer failure due to collection of un-oxidized particulates in the furnace. Reduces persulphate oxidation potential with concentration as low as 0.05%
Algae growth Does not impact the analyzer due to automatic self-cleaning feature. Collects in the sample system, leading to plugging.
Microfilters and pre-filter systems Eliminates the need for filtering due to 3.2mm sample tubes which handle up to 2 mm particulates. Requires filtering to prevent plugging of very small sample tubes (0.5 mm) and microsyringes. Requires filtering to prevent plugging of very small sample tubes and micro-slider valves.
Oils, fats and greases Self cleans in approximately 12-24 minutes. Must shut down analyzer to clean and maintain regularly. Loses measurement for approximately 12-24 hours.
Measurement drifts Allows a 6-month calibration interval due to TSAO method and high quality build. Requires calibration every 2-3 days due to furnace buildup and IR bench contamination. Requires calibration every 2-3 days due to UV light source scaling that causes incomplete oxidation and drift.
Automatic self-cleaning capability Includes automatic self-cleaning of the reactor and sample system with every reaction. Not available. Requires analyzer to be offline for 1 hour for manual cleaning.
