Abstract

A flame photometric detector for use with a gas chromatograph comprises a burner to produce a cool hydrogen flame and excite molecules of the gas sample to emit light characteristic thereof, a transparent chimney surrounding the burner and flame to enhance characteristic light emission, a selective light filtering means, and sensing means positioned so as to exclude the flame from its sensing area. The device and method of operation are characterized by a substantially broader range of detection and measurement than is possible with present commercially available equipment.
