EPAS (Quartz Enhanced Photoacoustic Spectroscopy) kits
and complete systems

Control and Data processing systems for Diode Laser Spectroscopy

QEPAS is a novel photoacoustic gas detection technique. The key QEPAS feature - using the high-Q quartz resonator as the acoustic signal detector instead of the conventional microphone. This gives new advantages to classic photoacoustic detection principles:

• Zero baseline drift for hours

• Miniature size of the absorption detection module (ADM)

• Superior absorption sensitivity per unit optical path length among all detection methods

• Absence of the adjustable elements in the ADM

• High dynamic range (from ppb level to 100% concentrations)

• The sensitivity is the same as for classic laser photoacoustic spectroscopy technique

• Low sensitivity to external acoustic noise

• Ultra small gas volume in the sensing element - near 1 mm³

The QEPAS ADM module. The NNEA (Normalized noise equivalent absorption) for NH₃ at 1.53 um is 3.3·10^-9 cm^-1W/Hz^-1/2. Ammonia detection limit in the air - 25 ppb for 10 second integration time.

QEPAS method was invented by A.A.Kosterev at RICE Quantum Institute in 2002, and then developed in close cooperation with CDP Systems Corp.
