An electronically controlled burner management system for oilfield separators. The system includes an autonomous standing pilot spark ignition that includes a self-aligning clamp that holds the igniter to the burner nozzle. The self-aligning clamp enables rapid installation and removal, lowering the total cost of ownership. The autonomous spark ignition system incorporates temperature sensors to determine when the standing pilot needs to be relit, and can shut off the gas or other fuel flow to the standing pilot and the main burner when the pilot is not lit. The system increases oil and gas production from the well, reduces fugitive emissions of unburned gas, and improves oilfield worker safety. When installed or retrofitted into an existing oilfield separator, the original burner control components are left in place, allowing the user to revert to traditional operation in case of failure of any electronic component of the present system.

Systems and methods for establishing and/or maintaining the prediction capability over time of a multivariate calibration model designed for quantitative optical spectroscopic measurement of attributes or analytes in bodily tissues, bodily fluids or other biological samples, which are particularly useful when the spectral absorbance of the attribute or analyte is small relative to the background. The present invention provides an optically similar reference sample to capture the characteristics of instrument and environmental variation and to reduce the effect of such variation on the measurement capability of the model. The optically similar reference is preferably stable over time and is designed such that its optical properties are sufficiently matched to the sample of interest that instrument and environmental variations are captured in the same manner in both the test sample of interest and the optically similar reference sample. The optically similar reference sample may include one or more physical components which are spectroscopically measured in a manner which closely mimics the spectroscopic measurement of the test sample of interest. Spectral similarity may also be achieved by using alternative components with spectral characteristics similar to the components contained in the test sample of interest.
