PA301

Ultra-high performance photoacoustic detector

Improves laboratory productivity and safety
For solid, semi-solid and liquid samples
The quickness and the ease of use

Photoacoustic FTIR accessory that enables rapid analysis of solid, semi-solid and liquid samples

Versatile analysis with ultra-sensitive photoacoustic FTIR accessory

The PA301 photoacoustic FTIR accessory 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, the depth profiling capabilities, and contactless measurement provide wide applicability in many areas of chemical and biological research which no other single accessory can match.

measurement

100x faster

than other PAS solutions

High quality spectra can be obtained in just seconds

Due to the ultra-high sensitivity of the Gasera novel cantilever sensor, high quality spectra can be obtained in just seconds unlike in other available photoacoustic accessories. In fact the PA301 is over 100x faster that other competing PA solutions in the market. Furthermore, 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 the PA301 a must-have accessory for every lab!
