Abstract
A mass spectrometer system for a mass spectrometer is provided. The mass spectrometer system includes a bellows system including a bellows configured to contain a gas and have an internal pressure within the bellows, and a housing configured to surround the bellows. The mass spectrometer system also includes a control system coupled to the bellows system. The control system includes a controller configured to continuously maintain the internal pressure of the bellows at a constant pressure within the bellows and cause, based on the continuous maintaining, delivery of the gas at the constant pressure from the bellows to the mass spectrometer. Related methods and articles of manufacture are also disclosed.
Claims20
A mass spectrometer system for a mass spectrometer comprising:
- a bellows system comprising:
- a bellows configured to contain a gas, wherein the bellows has an internal pressure within the bellows;
- and
- a housing configured to surround the bellows;
- and
- a control system coupled to the bellows system, the control system comprising a controller configured to:
- continuously maintain the internal pressure of the bellows at a constant pressure;
- and cause, based on the continuously maintaining, delivery of the gas at the constant pressure from the bellows to the mass spectrometer.
A control system for use with a mass spectrometer, the control system comprising:
- at least one data processor;
- and
- at least one memory storing instructions which, when executed by the at least one data processor, result in operations comprising:
- continuously maintaining an internal pressure of a bellows at a constant pressure, wherein the bellows is configured to contain a gas and be positioned within a housing;
- and
- causing, based on the continuously maintaining, delivery of the gas at the constant pressure and a constant gas flow rate from the bellows to the mass spectrometer.
