Abstract
A flame photometric detector of a gas-chromatograph is arranged such that a mixed gas of a column outflow gas and a fuel gas is ejected from a tip of a nozzle, and the mixed gas and supporting gas are mixed and burn inside a combustion chamber. Light with a particular wavelength is generated from a flame and detected. The flame photometric detector for the gas-chromatograph includes a cylindrical member disposed inside a fuel gas passage of the nozzle. It is possible to change an inner diameter or a height a tip of a nozzle by changing the cylindrical member.
