  • Solid dosage component measurement device and solid dosage component measurement method
    Patent number: 11467085
    Abstract: A solid dosage component detection method for a solid dosage component measurement device comprises generating a transmitting electromagnetic wave with a terahertz frequency and emitting to a solid dosage component; detecting a receiving electromagnetic wave with a terahertz frequency through the solid dosage component; comparing the transmitting electromagnetic wave incident on the solid dosage component with the receiving electromagnetic wave received from the solid dosage component to detect a plurality of signal characteristics differences between the transmitting and receiving electromagnetic waves; and discriminating polymorphism of a testing pharmaceutical in the solid dosage component, calculating a concentration of the testing pharmaceutical in the solid dosage component, and analyzing a coating layer thickness and a porosity of the solid dosage component based on the plurality of signal characteristics differences.
