Abstract

A method and a device for monitoring a property of a coating of a solid dosage form during a coating process forming the coating of the solid dosage form are provided. The device comprises a coating apparatus configured for forming the coating on the solid dosage form, and a monitoring apparatus configured for monitoring the property of the coating of the solid dosage form in process, wherein at least a part of the monitoring apparatus is located so as to have insight in an interior of the coating apparatus, the interior accommodating the solid dosage form to be coated and a precursor for forming the coating, and wherein the monitoring apparatus is configured for monitoring the property of the coating of the solid dosage form simultaneously with and during a coating process using low coherence interferometry.
