A small quantity of gas, usually at or close to atmospheric pressure, is sampled using an automated batch inlet. After expansion and consequent pressure drop the gas is analysed using a high sensitivity 500 amu quadrupole mass spectrometer.

Most minor components in the gas mixture can be measured at levels of 5 ppm or above.


- Dual compound turbo pumps and oil-free, totally dry backing pump

- Automatic dosing, expansion and accurate sampling

- Total sample pressure measurement with capacitance manometer

- Optional aliquot filling facility

- 1 litre sample reservoir

- 1 ml injection reservoir

- Optional calibration lines


The system is supplied with MASsoft 7 Professional Edition software.

This Windows 8 compatible software allows control of the instrument via USB 2.0, RS232 or Ethernet. Provides comprehensive I/O for data output and for reading data from external devices for integration and display with mass spectrometer data.
