Claim 9:
10. A method as in claim 9, wherein the spectroscopic analysis system comprises a reflector and/or a beam splitter configured to be inserted into a path of a beam emitted by the light source, the reflector directing at least part of the beam when inserted into the path such that the at least part of the beam passes through the wavelength/frequency calibrator and on to a detector for characterizing intensity changes resulting from interaction of the at least part of the beam with the wavelength/frequency calibrator, and wherein when the reflector is not inserted, the at least part of the beam is directed through the sample fluid and on to the detector or another detector for characterizing intensity changes resulting from interaction of the first portion with the sample fluid, which are recorded in the field spectrum.
