Residual gas analyzer / rack-mounted

This ionizer has been designed to produce enhanced sensitivity and to reduce background noise. A ion source that has limited conductivity is able to operate with sample pressures reaching 10-3 torr without the need for any extra reduction of pressure of the differentially pumped inlet system. Larger numbers of neutrals and more samples to ionize are contained in higher sample pressures.

The signal strength differs proportionally with the sample density as each order of magnitude increases in pressure. This is achieved with the confinement of a sample within a relatively small ionization volume. It works by constraining the sample within the ion volume which has two small slits on either side and bombarding electrons through these slits, ionizing the sample. The ions which form near the small exit hole of the ion volume will instantly be extracted into the mass filter, having little chance to react with neutrals.
