The LAR™ QuickTOCpurity™ water analyzer is the online TOC measurement system for the determination of total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC) and dissolved organic carbon (DOC)in pure water according to DIN EN 1484, ISO 8245 and EPA 415.1. Iit can easily satisfies the most stringent TOC monitoring requirements wherever pure water is produced or consumed. Some examples include Water for Injection (WFI) in biotechnology and pharmaceutical industry, boiler condensate reclaim in the power industry, RO and DI water for the microelectronics industry, and municipal drinking water treatment.

It has been engineered to work without the aid of expensive catalysts by using temperatures of more than 1,200°C, well in excess of the current state of the art for online thermal catalytic oxidation which uses temperatures of only 680° to 1,000°C. Operating at these temperatures enables it to quickly, completely oxidize even difficult-to-combust compounds, regardless of their composition.  Also, The QuickTOCpurity water analyzer can operate in a continuous batch mode, producing results every three to five minutes. This guarantees the detection of even brief, transient peaks throughout the day.

EASILY MONITOR ORGANIC LOAD AT 1,200°C 

The QuickTOCpurity water analyzer uses a high-temperature combustion process to dissolve all carbon bonds and convert organic carbon in ultrapure water to carbon dioxide (CO₂) for measurement.

When a water sample is injected into the analyzer, it is first acidified to a pH of about 2 to remove any inorganic carbonates that might be present. The sample is then passed through a combustion furnace that is heated to a temperature of about 1,200°C.

At this high temperature, all the carbon bonds in the organic compounds present in the sample are broken and the resulting carbon is converted to carbon dioxide (CO₂). This combustion process occurs in the presence of oxygen, which ensures complete oxidation of all organic compounds.

The CO₂ that is produced during the combustion process is then detected by an infrared detector, which measures the amount of CO₂ that is produced. The amount of CO₂ produced is proportional to the amount of organic carbon that was originally present in the water sample.

Finally, the QuickTOCpurity analyzer calculates the concentration of Total Organic Carbon (TOC) in the sample by multiplying the concentration of CO₂ produced by a conversion factor that takes into account the amount of sample that was analyzed and the dilution factor.
