Gasera - Model PA 301 -Ultra-High Performance Photoacoustic Detector for Solid, Semi-Solid and Liquid Samples
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.
- No sample preparation
- Contactless measurement
- 100x faster than other PAS solutions
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!
