! Photoacoustic effect was discovered in 1880 by Alexander Graham Bell
! This theoretical potential has not been reached, since conventional microphones have been used for sensing the pressure pulses
! Gasera’s novel cantilever sensor technology allows the use of the full potential of the photoacoustic phenomena
Photoacoustic spectroscopy is based on the absorption of light leading to the local warming of the absorbing volume element. The subsequent expansion of the volume element generates a pressure wave proportional to the absorbed energy, which can be detected via a pressure detector.

LASER PAS Reliable and cost effective gas analyzer products with down to ppb/ppt sensitivity in safety and industrial applications. Widely tunable lasers in MIR range enable multi-gas monitoring capabilities.
NDIR PAS Enables sensitive gas analyzer for multi-gas monitoring in industrial applications such as transformer condition monitoring, waste anesthetic gases and agriculture.
FTIR PAS Measures the full IR spectrum of the sample gas mixture and compares the result to library spectra of pure compounds. Enables sensitive and selective portable/hand-held gas analyzers for real-time simultaneous monitoring of over 50 gas compounds. Suitable for CEMS. process control and AQ.
DIFFERENTIAL PAS Enables a small and cost effective single or dual gas sensor with extremely high sensitivity and selectivity for fast open path measurements with response time below 0.1 seconds. Highly suitable e.g. for gas flux measurements, breath diagnostics, and tail pipe measurements

Benefits of cantilever enhanced PAS
- 9 -
! Absorption is measured directly in PAS which makes the measurement very accurate and free of drift -> stability and reliability, easy to use
! Cantilever sensor provides high sensitivity –> below ppb detection limits ! Sensitivity is not dependent on the optical path length -> wide linear dynamic range, miniaturization,
low sample volume ! Many different sources can be connected to one cell -> multi-gas capability ! Possibility to heat the sample cell -> suitable to wide range of process applications
