Abstract

A diode laser based natural gas leak detector has been developed that can measure methane concentrations over six orders of magnitude, from ambient (1.7 ppm) to pure gas levels. The detection method utilizes a small multipass cell and wavelength modulation absorption spectroscopy. At high methane concentration, various forms of unmodulated absorption spectroscopy are used. The instrument is a handheld unit that operates on less than 2 W of power and weighs 1.4 kg (including battery). A small pump on the unit pulls outside gas into the enclosed optical cell through an extendable probe. The response time of the instrument is approximately 1 - 2 sec.
