Protea is a UK-based instrument manufacture and systems builder specialising in spectroscopic gas analysis, using FTIR, TDLAS and QMS technologies amongst others. Our customer-focused analysis systems for process, emission and environmental monitoring can provide a solution for direct installation into a plant (such as CEM systems) or we can provide the analytical technology on an OEM basis to preferred system integrators for your own installations and packaged systems. We can provide core analysers for mobile or laboratory testing, or complete integrated systems with complex sampling systems for plant process and emissions.

Looking for distributors

We are looking for official distributors for local support in markets such as emissions, process, laboratory, research, ambient air and workplace gas analysis. We are looking for OEM system integrators with knowledge and access to local market needs in emissions, automotive and other specialists gas analysis applications.

Protir - Model 204M - Transportable CEM FTIR Gas Analyser

The 204M is a transportable CEM based on FTIR technology. It is MCERTS approved and used by stack testing organisations and laboratories for compliance and BS EN 14181 emissions monitoring. Using the 204M for measurements of waste incineration and combustion plant process is as simple using an FTIR can be. With pre-loaded calibration methods for 28 gas species, automatic nitrogen purging, in-built pressure and temperature alarms, analogue and digital I/O ...

Syngas analyser

atmosFIRi is a Fourier Transform Infra-Red (FTIR) analyser with a very small volume flow-through cell and a high throughput single pass gas cell. atmosFIRi is ideally suited to the measurement of CO, CO2, CH4 and other non-CH4 hydrocarbons in Syngas composition. There are no costly gold coated optics with in the gas cell, as long pathlength are not required. The analyser is designed to give quick response, with response times of


Measurement solution for siloxane measurement in land-fill gas via FTIR

What are siloxanes?

The generation of electricity from municipal digesters and land fill is of increasing interest, as the biogas generated is a form of renewable energy. Organosilicon compounds are often present in products such as shampoo and cosmetics, as well as industrial products and lubricants, and they move into land-fill. These volatile compounds find their way into land-fill or digester gases as siloxanes.

Measurement solution for QAL2 EN 14181

BS EN 14181 is a quality assurance standard relevant to plants operating under the Large Combustion Plant (LCPD) and Waste Incineration (WID) Directives. Quality Assurance Level 2 (QAL2) of this standard involves the parallel testing of the plant automated measurement systems (AMS) against a certified test house, making measurements with a comparative standard.


Protea Analyser Software (PAS)

Protea Analyser Software Protea Analyser Software (PAS) is Protea’s standard data acquisition and analysis package for laboratory and mobile field measurements of FTIR data.

Data Reporting Packages Software

Data reportingProtea understands that the results from your analyser are often just the start of what needs to be reported in your process application. Data formatting and manipulation can vary from industry to industry, application to application. This can mean sorting historical data or formatting live data as it is collected, ready for passing to another system in your process. Whatever your requirement, Protea can provide bespoke reporting ...
