Abstract: A method for maintaining one or more operating conditions within a battery operated flame ionization detector (BOFID). The method includes receiving one or more desired values that correspond to the operating conditions and receiving one or more measured values from one or more sensors configured to monitor the operating conditions. After receiving the desired values and the measured values, the method sends one or more commands to a controller disposed inside the BOFID to achieve the desired values based on the measured values.

Abstract: A method for calibrating a flame ionization detector (FID). The method includes receiving a request to schedule a calibration. After scheduling the calibration, a flow request command is sent to a gas distribution system at a scheduled calibration. The flow request command instructs the gas distribution system to provide a gas at a gas concentration level to the FID. After the gas distribution system provides the gas at the gas concentration level to the FID, the method includes receiving a raw count from the FID and correlating the raw count with the gas and the gas concentration level provided to the FID. The method then stores the results of the correlation in a calibration log.
