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.

Abstract: Methods and apparatuses, including computer program products, are described for measuring greenhouse gas. A calibration device receives a first sample of atmospheric gas from a first port exposed to the earth's atmosphere. The calibration device receives a second sample of atmospheric gas from a second port exposed to the earth's atmosphere. The calibration device routes the first sample and the second sample to a measurement device for greenhouse gas analysis. The measurement device determines a characteristic of a greenhouse gas present in at least one of the first sample and the second sample. The measurement device transmits data associated with the determined characteristic of the greenhouse gas to a computing device for determining sinks and sources of the gas.
