Sira is running a free workshop as part of the technical programme at the Photonics Conference 2003, which will focus on the evaluation of long-path optical techniques for real world applications.

The workshop will take place on Wednesday 8th October from 1345 to 1700, in seminar rooms 1 and 2, at the Warwick Complex, Stoneleigh Park, Warwickshire.

The workshop is aimed at all those with an interest in gas measurement using open path technologies including manufacturers, existing and prospective users and those representing certification bodies.

It is designed to present the most recent data available on best practice for siting and use of open-path optical instruments based on the results of the EU Remote Optical Sensing Evaluation (ROSE) project.

The ROSE project is aimed at evaluating the strengths and limitations of open path techniques through a unique programme of real-world field trials and controlled measurements.

A range of manufacturers, users and academics are brought together to understand the potential sources of error and effects of use under genuine measurement conditions.

The project is developing test equipment and an evaluation methodology, which may be used as the basis for a European standard.

The project brings together DOAS, FTIR, FTUV, TDLAS and DIAL-LIDAR techniques, which are used in a programme of field trials, controlled measurements and modelling.

Open path optical techniques are important methods in measurement of gas concentrations from parts per billion in ambient urban air to explosive limits in industrial installations.

Path lengths of tens to hundreds of metres are used in detection of diverse species from nitrogen oxides to volatile organic compounds.

The instruments available have distinct advantages over some other more conventional techniques, but their more widespread use is hampered since they are not included in current certification schemes.

The workshop will provide participants the opportunity not only to get informed about the results of the field trial programme, but also to comment on the evaluation methods and have an input into the proposal for the draft standard.
