Air-quality monitoring standard smells sweet

Aug 17, 2004

Sira Technology’s Environmental Business is working to push boundaries and maintain its reputation as a force in the field of environmental monitoring with the Remote Optical Sensing Evaluation (ROSE) project. This project seeks to define quality assessment and quality-control parameters, and evaluate performance of Remote Optical Measurement Techniques (ROMTs) in support of future EC standardization by determining best practice and performance standards.

ROMTs are becoming increasingly common in air quality and gas-sensing applications. ROMT uses real-time in-situ gas analysis to measure gaseous pollutants, guaranteeing results are as accurate as possible. This offers a number of advantages, including flexibility of deployment and avoidance of extractive sampling.


With increasing air-quality legislation and national and international strategies on the horizon, industries must have complete confidence in their monitoring systems. Unfortunately, many companies are reluctant to apply remote or open-path optical systems for formal monitoring purposes because there is a lack of standardization between systems. This has led to the introduction of a European initiative to determine critical performance factors for ROMTs.


The ROSE project assesses ROMTs in the context of the environments in which they are applied. The most significant element of this project is that it has increased available knowledge about ROMTs. This could lead to a wider use of remote optical measurement techniques in enforcement or compliance-monitoring applications.


Sira Environmental provides monitoring and conformity assessment solutions to a range of businesses in industries such as process, environment, manufacturing, oil, gas and petroleum. It services the environmental-monitoring community in the specific areas of emissions monitoring and gas/air quality analysis. The ROSE project has many applications, including urban air quality, transport, energy and process emissions.


Sira says the ROSE project has developed a firm theoretical foundation, which will support a set of best practice and performance standards. These standards can then be used to inform new EC directives in the future. The goal of the ROSE project has been to verify that remote optical instruments can be trusted to perform with a defined level of uncertainty. It has played a large part in demonstrating that specific instruments are compliant with one another.


Sira is heavily committed to providing expertise in the development, commercialization and support of instrumentation and measurement solutions. For more information on the services offered by Sira, please contact Bob Cooper, Sira’s environmental business director, at, or visit
