  • Method of monitoring a freeze drying process
    Patent number: 6848196
    Abstract: A method of monitoring a freeze-drying process in an apparatus (1) holding one or more samples (9) of a material to be freeze dried, comprises the steps of directing input radiation onto the sample (9), the input radiation forming output radiation by interaction with the sample (9); collecting at least part of the output radiation and leading the thus collected radiation to a radiation analyzer (11); and analyzing the collected radiation spectroscopically in the radiation analyzer (11) to obtain a measurement value of one or more freeze-drying parameters of the sample (9), such as the temperature of the sample (9) and/or the content of a solvent in the sample (9) and/or the structure of the sample (9).
