    Abstract: A method and system for gas sensor drift correction is disclosed, appropriate for use in a system placed in an environment that with some regularity reaches a background gas concentration. A background gas concentration range is defined. When the gas sensor readings drop below the background gas concentration range for at least a defined short dwell time, an upwards calibration adjustment is effected. When the gas sensor readings stay above the background gas concentration range for a defined long dwell time (longer than the maximum expected interval between excursions to the background gas concentration), a downwards calibration adjustment is effected.

    Abstract: System and method for calibrating a sensor comprises a detector capable of detecting electromagnetic radiation at least at a radiation wavelength of interest, an analyzer capable of determining concentration values in response to the detected radiation, and a calibrator capable of automatically calibrating the analyzer in response to at least one concentration value. A method for operating a calibrator comprises receiving an initiation signal capable of initiating the calibrator, automatically obtaining concentration values in response to the initiation signal, and automatically determining a calibration value from the obtained concentration values. In an embodiment, the calibrator automatically determines when a calibration gas equilibrates within a sample chamber.

    Abstract: A diffusion-type gas sensor is disclosed. The sample chamber uses a narrow slot as a gas diffusion port. The slot is advantageous as it can be formed during extrusion of chamber stock material, instead of during subsequent machining steps that are costly and may adversely affect the chamber surfaces. Further, the slot profile can be designed according to various profiles and/or positions that can improve gas diffusion, chamber reflection efficiency, or both, as compared to conventional ported chamber designs.
