Why Laser Gas Detection?

Very high spectral resolution (<0.01nm)

• Minimum interference from other gases
• Linear response over wide measurement range
• Intense light source
• High signal-to-noise and rapid response - typically < 1 sec
• Long path lengths possible (to 1000m)
• Very sensitive – ppm to ppb levels
• Lasers available throughout NIR
• Can be used with many gases
• Soli

Abstract

Laboratories have a professional obligation to provide accurate and reliable analytical results to customers. The Laboratory should to justify the customer’s trust by providing the correct answer to the analytical part of the problem, in other words, results that have demonstrable ‘fitness for purpose’ Analytical method validat

Primary aluminium smelting generates large amounts of hydrogen fluoride gas (HF). Concerns for worker safety and ambient air quality require that HF be monitored at several locations in smelters. Historically, a variety of methods have been used for HF monitoring. Cassette samplers and wet chemistry techniques, coupled with complex and expensive sampling manifolds have monitored roof-line and scrubber duct HF levels. In recent yea

Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is proportional to the concentration.

This is a low concentration detector, use
