Principal component analysis of Raman spectra for freeze-drying process monitoring
Optical spectral measurement tools are extremely useful both for in-line measurements in process analytical techniques (PATs) as well as for evaluating the composition of finished substances. Here, CPI’s Lukas Kuerten and Rachel Findlay demonstrate a valuable method for gaining useful information from spectral data.
