1. A flame ionization detector, comprising:
a burner combusting 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 configured to measure an ion current from the gas flame to an electrode;
a temperature sensor configured to measure a temperature of the gas flame; and
an evaluation device configured to evaluate the measured ion current and to compensate 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.
