Raman process analyzer calibration transfer through analyzer standardization

As Raman spectroscopy finds increased utilization for on-line measurement, the issues of analyzer stability and calibration transferability grow in importance. This paper presents a method that allows calibrations developed an one analyzer to be transferred to others located at the same or different sites. This method also allows maintenance of calibrations in a single Raman analyzer overtime even when critical components are altered. Calibration transfer eliminates the need to develop calibrations for different analyzers and upon analyzer repair, saving time and money in calibration model development and maintenance.
