TOC ANALYZER MODEL B3500C

Basic features of Hach B3500C

No more worries about TOC

With patented, two-step advanced oxidation technology, the B3500c provides you with maximum uptime and reliability without sacrificing accuracy.
Lowest cost of ownership
Only requires reagent replacement, pump tube replacement, and calibration twice a year. The Hach BioTector B3500c is currently the TOC analyzer with the lowest operating cost.
Compact unit = significant space saving
As the most compact analyzer, it maximizes wall space, freeing up space for other equipment.
Insignificant reagent costs Only requiring reagent replacement every 6 months, you will see significant savings compared to other systems

Allows monitoring of two sample streams simultaneously, eliminating the cost of equipping two independent machines.

Operating principle of Hach B3500C

TIC
Acid is added to lower the pH to drive inorganic carbon components into CO2 gas. This determination step ensures that Total Inorganic Carbon (TIC) is not carried over into the TOC determination step.
Oxidation
BioTector with TSAO oxidation method achieves complete oxidation of the sample containing organic carbon into CO2. TSAO utilizes hydroxyl radicals generated by combining oxygen passed through an ozone generator reacting with NAOH.
TOC
To remove CO2 from the oxidized sample, the pH of the sample must be lowered again. The CO2 gas is blown into the NDIR CO2 measuring chamber. The result displayed is Total Organic Carbon (TOC).
