TOC Analyzer

Features of Online TOC Analyzers

Unique, Patented Two Zone Furnace Design

Having two temperature zones assure complete combustion of carbon and nitrogen containing compounds while saving the catalyst life. This is based on the unique patented two-zone furnace design. Reactor design eliminates direct physical contact of the catalyst with the sample, reducing sulphur and halogen poisoning, thereby increasing catalyst service life.

Simultaneous Nitrogen Analysis Is An Option

High temperature catalytic oxidation (HTCO) technology and the in-house developed catalyst allow simultaneous measurement of TC and TNb parameters. The same catalyst serves for combustion of compounds containing carbon and nitrogen.

Ease Of Maintenance

Design of TRL-onlineTOC Analyzer simplifies maintenance. Software generates warning messages for routine maintenance needs allowing the operator to recognize, remotely and take action in time. Maintenance and adjustment requirements are collected in a panel for easy access to each component.

Low Cost Of Operation As Well As Very Low Maintenance Needs

Long catalyst service life as well as extended life of consumable items allow maintenance free 80 days operation, based on hourly monitoring.

Operator Friendly Software Functions

Maintenance chief and technicians can be listed in hierarchy of users and be classified in distribution of authorities. All events are logged and permanently saved. All settable parameters are under the control of the chief and any change is logged, in case. Graphical display of trend is easy to generate on the screen.

Specifications Of TRL-onlineTOC Analyzers

The monitor is designed for continuous operation
