Instruments RAD Spectrometer  Sensitivity demonstration

Example of recording demonstrating RAD spectrometer sensitivity


“Forbidden” transitions of AsH3 molecule recorded by RAD spectrometer.
The spectrometer sensitivity can be calculated using the line maximum absorption coefficients (shown above) and the record signal to noise ratio as:
