1. A spark stand for an atomic emission spectrometer, comprising:
a spark chamber;
a gas inlet for flowing gas into the spark chamber; and
a gas outlet for carrying gas from the spark chamber;
wherein the spark stand is adapted to be decouplable from a stage at the atomic emission spectrometer, to permit removal and exchange with another spark stand;
wherein the gas inlet at the spark stand is connectable to a gas outlet on the stage at the atomic emission spectrometer and the gas outlet at the spark stand is connectable to a gas inlet on the stage at the atomic emission spectrometer;
wherein the spark stand is configured for tool-less coupling and decoupling from the atomic emission spectrometer stage.
