Introduction
The photoacoustic detector improves laboratory productivity and safety by enabling extremely versatile and rapid analysis of solid, semi-solid, and liquid samples in any form without sample preparation.
The insensitivity to sample surface morphology and the depth profiling capabilities provide wide applicability in many areas of chemical and biological research which no other single accessory can match.
Due to the ultra-high sensitivity of the Gasera’s novel cantilever sensor, ambient air can be used as the carrier gas to obtain a signal-to-noise ratio (SNR) that is still significantly better compared to other commercial photoacoustic detectors used with helium carrier gas. The quickness and the ease of use make this product a must-have accessory for every lab.
Photoacoustic spectroscopy directly measures a sample’s infrared absorption. The absorption of infrared radiation in the sample creates heat which is transferred into the surrounding gas and a photoacoustic signal is generated via thermal expansion. Thus the measurement is non-destructive and the signal is independent of the surface roughness. The measurement depth can be controlled by varying the mirror velocity or phase angle of detection, and thus depth-varying information can be obtained.
The heart of the system is the patented optical microphone comprising of a MEMS cantilever coupled with a laser readout interferometer that can digitally measure microscopic movements of the cantilever sensor, having a dynamic range greater that any analog circuitry can ever obtain.
