Abstract:
1. A time efficient method of analyzing sample systems with spectroscopic electromagnetic radiation comprising wavelengths which are not absorbed by oxygen and/or water vapor and wavelengths which are absorbed by oxygen and/or water vapor, comprising the steps of: in any functional order practicing steps a, a′ and a″: and then proceeding to practice steps b and c and d: such that during the evacuation or purging process, while oxygen and/or water vapor is still present in said substantially enclosed space in sufficient quantity to absorb said wavelengths which are absorbed by said oxygen and/or water vapor, data is provided by said detector means for wavelengths which are not absorbed by oxygen and/or water vapor, and such that once said substantially enclosed space is sufficiently evacuated or purged of oxygen and/or water vapor, data is provided by said detector means for wavelengths which are absorbed by oxygen and/or water vapor.
