Abstract: The present invention relates to a method of improving a mass spectrometer, a module for improving a mass spectrometer and an improved mass spectrometer. The aforementioned method uses machine learning and can greatly reduce the number and timeframe for the elimination of false positives to a couple of hours. Such method can be integrated into a mass spectrometer by inserting a computer module programmed with such method into a mass spectrometer's computer system.

Abstract: An aircraft air quality testing system includes a portable housing unit to be removably placed within an aircraft; an air testing unit secured inside the portable housing unit and including: a sensor to receive an air sample during a plurality of oxygen generation system cycles and engine thrust settings of the aircraft; a removable collection media to receive the air sample from the sensor and filter targeted chemicals from the air sample; and a plurality of analyzers to perform a real-time chemical analysis of the air sample and the filtered targeted chemicals. A first computer is operatively connected to the portable housing unit and includes: a processor to receive the real-time chemical analysis and generate real-time chemical analysis and flow rate data; a memory device to store the real-time chemical analysis and flow rate data; and a display device operatively connected to the portable housing unit.

Abstract: A self-timing, passive, chemical dosimeter. The dosimeter includes a sampling media and electronics supported by a cassette. The sampling media is configured to absorb volatile organic compounds, semivolatile organic compounds, or both, while the electronics are configured to record a time of exposure. The dosimeter further includes an actuator having a closed position and an open position. In the closed position, the actuator resists exposure of the sampling media to volatile organic compounds, semivolatile organic compounds, or both, and in the open position, the actuator permits exposure of the sampling media to volatile organic compounds, semivolatile organic compounds, or both. The actuator is configured to operate the electronics for recording time of exposure.
