Assignee: ENDRESS+HAUSER OPTICAL ANALYSIS, INC.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 7:
8. A method as in claim 6, wherein the spectroscopic analysis system is configured to direct at least a first portion of a beam emitted by the light source such that the first portion passes through the sample fluid and on to a first detector for characterizing intensity changes resulting from interaction of the first portion with the sample fluid, which are recorded in the field spectrum, and wherein the spectroscopic analysis system comprises the wavelength/frequency calibrator positioned to receive light emitted from at least one second reflector of a light source and/or a back facet of the light source and/or by high reflector leakage from the light source, the spectroscopic analysis system further comprising a second detector for characterizing intensity changes resulting from interaction of the light with the wavelength/frequency calibrator.
