Short Communications


A device for optimizing the flow rates of hydrogen and combustion air to flame ionization detectors is described. The method is based on feeding an auxiliary gas containing a small amount of methane into the detector and changing the flows of the combustion gases. The optimum flow rate is determined by peak height comparison rater than evaluation, of signal-to-noise ratios.
