Application of Tunable Diode Laser Absorption Spectroscopy (TDLAS) to Monitoring Pharmaceutical Lyophilization

This white paper provides an overview of Tunable Diode Laser Absorption Spectroscopy (TDLAS) and its application for monitoring freeze drying processes. Through the combination of TDLAS measurements and a well-established heat and mass transfer model describing freeze drying, users can obtain information about Key Process Parameters (KPPs) affecting end product quality.
