Mass spectrometer
Mass spectrometer
Measures the concentration of gases and vapours in real time
Mass range 200 or 300 amu
Minimum detectable concentration 100 PPB
Maximum detectable concentration 100%
Sample inlet pressure 100 mbar to 2 bar abs
Sampling inlet Heated flexible silica capillary
Standard capillary length 2 meters
Response time to gas concentration change 300 milliseconds
Fast measurement speed Up to 650 measurements per second
Sample flow required (Standard) 16 atm cc/min
Sample flow required (Optional) < 1 atm cc/min to > 20 atm cc/min
Corrosive gas sampling possible. Concentration needs to be kept in low ppm-region (<1.0E-7); apply extensive gas purging procedure with inert gas.
