Abstract
Optical spectroscopy in a purging atmosphere wherein an optical accessory is gas-tight coupled in the spectrometer sample compartment to the open beam port of the spectrometer, whereby the same purging gas used by the spectrometer can be employed to purge the accessory. Where the accessory allows external sample placement or external adjustments, rapid sample changing or adjustment is possible without breaking the purge seal. In another embodiment, the accessory has its own purge inlet and sealed windows for receiving the spectrometer beam.
