Abstract
A hydrogen gas analyzer having an improved delivery system is provided wherein a plurality of branched passageways can supply a sample cell and an additive fuel to a combustion chamber. Cutoff valves can be activated to control the flow rates through the respective passageways so that when the concentration of hydrogen in the sample gas is high, the flow rate from the additive fuel will be reduced, and when the concentration of hydrogen is low, the flow rate of the sample gas is reduced.
