Purity of Boiler Condensate is Critical - TOC Analysers can highlight problems quickly and effectively

Steam and Hot Water are key processes involved in crude oil refinement & power plants. Contamination leads to costly corrosion within boilers, heat exchangers and pipework. The right TOC analyser can identify evidence of such corrosion and leaks quickly generating alarms and divert valves.

The LAR High temperature TOC analyser has a proven track record for this application with the following factors key for its success:

• Quick TOC Condensate version - programmed and configured for the application
• Multi-loop injection ideally suited to oily samples High Temp 1200 oC
• Catalyst-free oxidation resulting in full recovery of intransigent organics
• Minimal memory effects POC and VOC included in measurement
• Simple to validate with calibration gas or standards

Peaks and Troughs can be detected quickly

If a TOC peak is detected, it is important to be sure that it is genuine. Using liquid calibration standards is difficult due to stability issues, so the Quick TOC Ultra Calibration provides a fully automatic validation of the system using a certified gas. Such a test gas is stable for a long time and is ideal for automatic calibrations.

However, the innovative method enables the use of liquid standards if required. Also cross-contamination of the sample in the loop system is practically impossible.
