Embodiment 1
[0030] The present embodiment provides a kind of method that utilizes terahertz time-domain spectroscopic technology to detect sunburn myrrh, which comprises the following steps:
[0031] 1), sample preparation: the sample used is the full-ingredient traditional Chinese medicine sunburned myrrh granules produced by Beijing Kangrentang Pharmaceutical Co., Ltd. Weigh about 60 mg of sunburned myrrh granules with an electronic balance, and then grind them into fine powder in a mortar shape, and then set the shape in the tablet press, the pressure is increased to 5 tons, and the time is 8 minutes, so that a disc with a diameter of 13 mm, smooth on both sides, and a thickness of less than 0.4 mm will be obtained.
[0032] 2) Sample test: Turn on the laser until the output power is stable, calibrate the light collimation in the optical path; turn on the laptop, set the measurement parameters on the program panel of the terahertz spectroscopy system software, and measure after the lase...
