Abstract Correlation spectroscopy can be used to describe the linear correlationship between the absorbance and concentration data in the whole spectra range and clearly figure out the characteristic peak position of the sample under test. Meantime, this chart plays an extremely important role in offering the precise information for choosing the optimal wavelength set during the calibration process. Multiple scatter correct (MSC) spectroscopy is a kind of multiple variable scatter correction technique, and can effectively remove the base shift and tilt phenomenon caused by MSC. As a result, the ratio of signal to noise is improved greatly. Based on this feature, the new idea of the MSC technique was introduced into the preceding data treatment for the creation of correlation chart, and through careful experiment this idea was proved to be correct and effective.
