VOC Emissions Monitoring

VOC Emissions Monitoring

Multiple VOC Analysers

Protea has used our VOC gas analysers in many projects requiring the monitoring of complex mixes of VOCs. In the chemical and pharmaceutical industry, VOC abatement plants such as scrubbers and carbon-bed systems are typical installations where the use of Protea analysers and our VOC analysis expertise have proved valuable to plant operators. They prove a very powerful and flexible tool in both process gas measurements and VOC emissions monitoring. In the laboratory, Protea can deliver instruments with all the chemometric software and support to enable users to measure hundreds of gases.

Protea can deliver products for use either as portable VOC analysers or fixed VOC emissions monitoring systems, giving plant operators or emissions testers the powerful capabilities of FTIR is easy to deploy packages. For the trained FTIR user in the lab or the field, full spectrum libraries and model building software allow analysers to be configure and re-configured again and again to measure an almost infinite range of gas applications.

VOC monitoring of the following gases can be made easily made with our FTIR gas analysers, but there is almost no limit to the number of VOCs that Protea’s gas analyser can measure:
