摘要： A method for performing quartz-enhanced photoacoustic spectroscopy of a gas, includes providing a light source configured to introduce a laser beam having at least one wavelength into the gas such said at least one molecule within in the gas is stimulated generating an acoustic signal, accumulating the acoustic signal in a resonant acoustic detector, generating a resonant absorption signal (SA) relative to the gas concentration by at least one tuning fork serving as resonant acoustic detector, generating additionally a resonant intensity signal (SI) proportional to the intensity of the laser beam travelling through the gas, and providing an output signal (SGC) from said absorption signal (SA) and said intensity signal (SI) being independent of the intensity of the light relative to the presence or concentration of the gas.

摘要： A gas detection laser diode device and gas detection unit including the gas detection laser diode device having a hermetically sealed housing with electrical connectors at the bottom and a window, and inside the housing a laser diode and thermistor mounted on one stage of a thermo element. The thermo element is connected with the other stage to the base of the housing. Collimating means are arranged in the laser beam between the laser diode and the window. The window is tilted in respect to the axis of the laser beam such, that the ordinary reflection of the laser beam is steered off the laser beam axis and at least does not impinge on the laser diode. Preferably the collimating means and the laser diode are mounted on a same surface for holding them on the same temperature. The new device allows the detection of toxic gases with reduced detection limits over the prior art. The arrangement further claims a method to achieve reduced detection limits for gases.
