ProCeas – Air Quality Analyser

ProCeas®

Air Quality Analyser

The ProCeas® is a complete pre-calibrated multi-component analyser based on the enhanced IR Laser Spectroscopy method OFCEAS. The ProCeas® features the association of a performant spectrometer with a Low Pressure Sampling (LPS®) system (50-100 mbar absolute) for the online analysis of several key gases in industrial, environmental and OH&S applications. The association of the OFCEAS and LPS® technologies enables high spectral resolution, interference free, fast and sensitive analysis, regardless of the matrix of the gas to be analysed. Thanks to the low sampling pressure (100-50 mbar), the ProCeas® system fits a large range of applications without the need to heat nor dry the sample prior analysis reducing considerably installation, operation and maintenance related costs. The ProCeas® is a true direct extractive process gas analyser developed and patented worldwide by AP2E (France).

ProCeas® Exclusive features

Realtime Monitoring system (No sample treatment) 50 – 100 mbar abs. sampling pressure removes any risk of chemical adsorption, desorption and condensation along the sample line.	Low maintenance – The LPS® system allows flow low rates within 3 and 9l/h without affecting the response time and reducing considerably dust and materials build-up.
Interferences Free – OFCEAS technology provides exceptional selectivity, enabling simultaneous monitoring of multicomponent without interferences, regardless of the gas matrix.	Ease of integration – The ProCeas® allows digital (Ethernet, RS485, RS232, ModBus) analogue and TDR IOs.
No Drift and extremely low Limit of detection– The zero is contained in the signal, enabling automated and intrinsic zero drift compensation.	Field proven – The ProCeas® is free of optical moving part and was designed and built strictly for industrial and on-board mobile applications.

LPS® – Low Pressure Sampling

Simplified Sampling
No Sample heated line required to prevent condensation for most applications: low power consumption, no related ongoing maintenance

Cost effective sampling solution for complex applications (multipoint CEMS, redundancy, long length of sample line…)

Standard LPS system (unheated) comply with ATEX standards

The low volume of sample extracted for the analysis prevent contamination of the sampling line and minimise dust buildup on filters
Direct Extractive
True Real Time Air Quality Analyser (no dryer or scrubber)

No risk of absorption/desorption

The integrity of the sample is preserved
High performances
High Spectral definition: Low pressure accentuate the gas fingerprint

Extremely fast response time

OFCEAS, CONTINUOUS INFRARED LASER SPECTROSCOPY TECHNOLOGY

Starting in 2012, AP2E launched the industrialisation of the ProCeas® and LaserCEM® online multigas analysers using OFCEAS* patented laser spectrometry. This analyser range is based on several innovations, providing very high performance in terms of response time (less than a few seconds), accuracy (wide dynamic range from ppb to %) and reliability (no drift, 5 years MTBF)

The OFCEAS technology essentially differs from the CRDS (Cavity Ring Down Spectroscopy or Spectroscopy by resonance damping time) technology by its feedback principle: a part of the emitted radiation is returned from the chamber to the laser, enabling the tuning of the laser and the cavity resulting a resonance phenomenon. With a volume of only 15 cm3, the measuring cavity or cell is equipped with mirrors whose reflectivity exceeds 99.99%, providing an optical path between 1 and 10 km (approx. 10 meters in conventional technologies). The immediate consequence of this phenomenon is the identification of very intense absorption peaks with a very narrow spectral width. Given that the source used is a continuous laser, the system presents very high measurement stability: there is no zero drift and no need for new calibrations.

Optical Feedback Cavity Enhanced Absorption Spectroscopy: technology developed and patented by the University Joseph Fourier (France), coupled to a Low Pressure Sampling(100 mbar absolute) developed and patented worldwide by AP2E, for the on-line analysis of different gases. By the end of 2010, after two years of R & D studies, the AP2E ProCeas®was the award recipient of the USA “R & D 100” which rewards the 100 most innovative global technologies of the year.
