Kurzfassung

A UK company offers a system for generating precise, repeatable and highly accurate trace concentration gas standard mixtures. Already on the market, the compact, easy to use unit offers excellent stability with broad applications in security, health & safety, environmental, R&D etc. The use of proven permeation tube technology eliminates the need for multiple gas cylinders, reducing costs, saving space & removing a safety hazard. The company is seeking additional academic/industrial partners.

Details

Permeation tube technology provides a highly reliable and cost effective method of producing stable and accurate gas concentrations. The tubes enable the generation of vapor from solid, liquid and gas phase standards with fully adjustable concentration levels ranging from parts per million (ppm) to parts per billion (ppb). Permeation tubes comprise a small quantity of the chemical sealed inside a short length of fluoropolymer tubing (see Figure 1). The tubing wall serves as a permeable membrane through which the pure sample diffuses at a known rate. Precise temperature and flow control of the external air/nitrogen feed gas provides a pure, stable and repeatable output.

The system can replace multiple gas cylinders resulting in significant cost and space savings as well as eliminating hazards associated with cylinders.

Complex gas mixtures can be accurately generated through the use of multiple tubes. The gas generator platform is an ideal tool for numerous applications, ranging from calibration of explosive detectors in military and homeland defence to validation of personal monitors in industrial health and safety.

The system is supplied with an easy-to-use concentration calculator to determine operating and calibration points.

Innovative Aspects:
The patented permeation tube technology ensures accurate, precise and safe gas generation, fully adjustable within the ppm to ppb range. It is portable with a compact footprint and delivers superior long term stability and repeatability with high accuracy and precision, even at the lowest concentrations. The generator is suitable for a large number of available analyte compounds, including solids and liquids as well as gases. Other advantages include:
•Easy generation of multi-component mixtures using combinations of tubes,
•Reduced setup time and rapid generation of blended gas mixtures,
•Cost and space savings and elimination of hazards associated with multiple high pressure cylinders,
•Small quantity of target chemicals reduces risk of dangerous exposure,
•Fast and easy sample replacement,
•Quick and easy to generate blended gas mixtures.
