Supply of Gas Standard Generation System to Health and Safety Executive

About

The Health & Safety Executive awarded a contract to IAS GmbH for the supply of a gas standard generation system.

The system is required for the calibration and validation of air sampling methods, sampler devices, sensors, and the production of laboratory proficiency test samples.

It must produce stable standard gas atmospheres for inorganic and organic gases based on ISO 6145 procedures, including evaporation of a metered liquid standard, metered liquid delivery via mass flow controller or syringe injection, an evaporation unit heating to at least 150°C, digital mass flow controllers for carrier and diluent gases, a heated transfer line, and flow path materials compatible with organic solvents.

Desirable features include an RS-485 communications module for remote PC control via LabVIEW, a humidity control module (20-90% RH), and expandable modular design.

The contract value was £51,810.
