摘要
A flame ionization detector includes a burner to combust an oxygen-containing sample gas in a gas flame in the presence of air and while supplying a hydrogen-containing combustion gas. A measurement device measures an ion current from the gas flame to an electrode, and a temperature sensor measures a temperature of the gas flame. An evaluation device evaluates the measured ion current and compensates during evaluation of the measured ion current for a cross-sensitivity of the ion current to oxygen in the sample gas using the measured temperature of the gas flame.
