Keywords: "Process Analytical Technology", "multivariate calibration", Marbach and VTT

An alternative approach uses physical methods to estimate the spectral signal and statistical methods to estimate noise.

Editor’s Note: In Part 1 of this article, the author introduces science-based calibration (SBC) and provides some theoretical background, a summary of the method, an example of its use and a discussion of its advantages. In Part 2 (Pharmaceutical Manufacturing, February 2007, p. 44), Marbach will focus on the method’s applicability and limitations, as well as the specificity of response.
