Self-contained sampling control for use with Protea core gas analysers. The control of the gas sample in any analysis system is critical. From heated sample lines and probes to pump control, the management of the system is important to stop any damage to analytical hardware. For this reason, Protea supplies the Sampling System Control Module (SSCM) with our range of FTIR, TDLAS and Mass Spectrometer core analyser systems.

For complete Continuous Emission Monitoring Systems (CEMS) or continuous process analyser solutions, Protea can provide out core analyser technology integrated with suitable sampling system control in a cabinet.

Protea’s range of core gas analysers use Windows-based PCs for analyser control and data storage. For use in industrial process and emissions measurement applications a rugged and robust analyser controller is required.

In order to accurately calibrate Protea's range of gas analyser products, it is important to have repeatable gas calibration system. Protea’s gas blender products can achieve large calibration ranges to be covered from higher concentration gas reference standards. Using the latest in Mass Flow Controller (MFC) technology, the units are self-contained with embedded PC controller. The units can deliver calibration gas flows between 0-5lpm. The...

atmosFIR is the successor to Protea's previous emissions monitoring FTIR systems, keeping all the features that users found valuable in achieving their measurement results, but offering the benefits of the new atmosFIR platform with increased portability, lower ownership costs and increased measurement performance. atmosFIR can be considered a simple multi-gas analyser for combustion gas measurements; indeed for some users that is all it will be and...

atmosFIRi is a new concept in FTIR. The unit is designed as a general gas analyser that is simple to use, portable and a very low cost product that provides real-time online measurement suitable for plant systems. Often, gas monitoring applications require high concentration and quick response, and low level detection limits are not necessary. atmosFIRi has achieved low cost through a simpler design suitable for these applications, from low ppm up to...

Introducing Protea's new range of laser gas analysers - Solus. The Solus platform represents an extension of Protea's spectroscopic gas analysis equipment into laser based technology, allowing for highly selective, quick response and low range measurements of 1 or 2 gases in a cost-effective, re-configurable package.

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...

Quadrupole Mass Spectrometer Analyser System for low volume, quick responding gas measuring with large dynamic range Protea’s ProMass analyser is a compact, robustly designed semi-portable Quadrupole Mass Spectrometer (QMS) instrument incorporating all the latest mass spectrometer and vacuum pumping technology. ProMass can be supplied in portable carry case or a 6U 19” rack module for on-line process measurements. QMS is a useful mechanism...

atmosFIR is the latest generation of gas analyser technology from Protea. The atmosFIR system improves upon previous FTIR technology and represents one of the most cost-effective and flexible analytical products on the market today

For a complete transportable measurement solution of up to 10 sample points, the Solus Multipoint analyser is ideal for ambient air and livestock monitoring applications. Using a proven TDLAS sensor, the Solus Multipoint is combined with integrated sampling system for 10 sample points within the one transportable case. A 10-way valve manifold using non-corroding sampling parts can allow for automatic sequenced sampling for multiple points on-site. The...

Protea supplies heated sample lines of lengths 1m to 50m for the sampling of gaseous samples where sample temperature control is imperative. With dedicated integrated calibration lines and robust end fittings, these lines are suitable for fixed or mobile applications. Protea also supplies ATEX approved heating elements for our heated lines, enabling sampling to be made from zoned areas.

Fixed or mobile sample probes, stainless steel or PTFE lined, Protea is able to provide a solution to measurement from any sample point. With integrated sample filters of ceramic, PTFE, or microfiber construction these probes ensure that the sample passing to the analytical equipment is of sufficient quality to enable long life of equipment.

For measurement of gases that do not require hot measurements, Protea can supply sample probes of various material construction. This includes probes made of materials such as PEEK allowing for measurement of possible corrosive gases.

For customers with specialised gas measurement applications, Protea can provide customised sampling parts in order to ensure the requirements of each application are met. This can include unique arrangements of valves, filters and probes that can be supplied of the correct choice of materials and construction to ensure long-life and low downtime for the analytical system.

For gas sampling, Protea can provide sample lines of PTFE or PFA of various diameters and lengths at low cost. Sample lines can be provided 'bundled' into sets with gas fittings installed, ready to be used out of the box.

Protea’s gas analysers are extractive gas analysers and as such we need to ensure repeatable, consistent sample flow is provided to the equipment. The choice of pump is of great importance to ensure high uptime of analytical equipment. Protea can supply low-cost, low flow sample pumps for mobile applications. For sampling of corrosive gases, correct choice of pump diaphragms and seals is required and Protea can supply based on our...

Filtering of gas for particulate matter is of great importance to ensure high uptime for gas analysers and sample pumps. With Protea’s experience of process and emissions monitoring of many different applications, we can recommend the best choice of filter material and porosity. With our advanced FTIR gas analysers we are able to source and supply filters that show little off-gassing, which can often be a problem for some filters...

Fourier-Transform Infra-Red spectroscopy is a full-spectrum analytical technique that allows all IR absorbing species to be detected and measured by a single instrument. Protea has been at the forefront of FTIR technology in process and emissions measurement and prides itself on making the relatively complex operation of FTIR as simple and useful as possible. The make-up of an FTIR analyser is of a modular design – infra-red source,...

For highly selective gas measurements of one or two gases, Tunable Diode Laser Absorption Spectroscopy (TDLAS) has been introduced by Protea into compact and easy to use industrial gas analyser systems.

Mass Spectrometry is a useful mechanism for gas analysis in process applications, being able to detect and measure almost all gases with low detection limits and fast response. A mass spectrometer measures the mass-to-charge ratio of the molecules in a sample and by collecting and analysing the mass spectrum we can identity and quantify which molecules are present.

For measurement of oxygen (O2), the zirconia (ZrO2) lambda sensor is used by Protea. This sensor responds to the difference in oxygen concentration on the sample gas side of the sensor, compared to the reference side (ambient air). This response manifests itself as a non-linear induced voltage. This voltage is linearised and calibrate via electronics to give a concentration reading in %Volume. The zirconia sensor is ideally suited...

For spectroscopic absorption measurements of gas and liquid phase samples, correct choice of gas cell is paramount. Protea can supply a complete system with optimum sample cell, or we can provide a sample cell for your current instrument. We can provide FTIR gas cells, laser gas cells, FTIR liquid cells and process flow cells.
