LUBRICANT FLATTING ANALYZER, METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To precisely measure a flatting state of a lubricant.SOLUTION: A lubricant flatting analyzer 1 determines a flatting state of a lubricant on a measured object 2 in which particles forming a tablet (excipient: lactose) and the lubricant are mixed. The lubricant flatting analyzer 1 comprises: an electromagnetic wave output device 12 for outputting an electromagnetic wave of a frequency of 20 GHz or more and 500 THz or less; an optical element 14 having a full reflection face 14a for fully reflecting the electromagnetic wave, and an evanescent wave generated from the full reflection face 14a being received by the measured object 2; an electromagnetic wave detector 18 for detecting the electromagnetic wave which is fully reflected by the full reflection face 14a; and a flatting determination device 20. The flatting determination device 20 determines a flatting state of the lubricant, based on a change in reflectance ratio of the full reflection face 14 to passing of a mixing time. An absorption ratio of the electromagnetic wave in a predetermined frequency area of the particles is higher than an absorption ratio of the electromagnetic wave in a frequency area other than the predetermined frequency area of the particles.SELECTED DRAWING: Figure 1
