A Non-Destructive Terahertz System and Method For Capsule and Liquid Medicine Identification

Abstract
The medicine and drugs has in the past been manufactured to the final products and then used laboratory analysis to verify their quality. However the industry needs crucially a monitoring technique for the final batch to batch quality check. The introduction of process analytical technology (PAT) provides an incentive to obtain real-time information about drugs on the production line. The optical characterization techniques such as mid-infrared (MIR) and near-infrared (NIR) spectroscopy, Raman spectroscopy and imaging with the use of chemometric techniques have been used to quantify the final product. However, the spectra obtained from those characterization techniques containa lot of amalgamation and bands from the fundamental vibrations observed, making analysis difficult. In this work, we describe a non-destructive system and method for capsule and liquid medicine identification, more particularly, using terahertz time-domain spectroscopy and/or designed terahertz portable system for identifying different types of medicine in the package of capsule or in liquid medicine bottles. The target medicine can be detected directly, non-destructively and non-invasively. Keywords - Terahertz, Non-Destructive, Non-Invasive, Chemical Identification
