Abstract
Absorbance and wavelength data which is generated by a liquid chromatography apparatus is orthogonalized and resampled by a cubic splining technique in order to provide a smooth spectra curve showing absorbance versus wavelength, with the time factor eliminated. This has the advantage of eliminating from the data any changes in the sample over time. The method results in the orthogonalization with respect to time of the data. The invention is applicable to analysis of data other than liquid chromatography data. Higher or lower order curve fitting techniques may be used instead of the cubic splining analysis method.
