BIOLOGICAL SAMPLE DETECTION METHOD BASED ON CONTINUOUSLY ADJUSTABLE BIOLOGICAL SAMPLE HOLDER

摘要

A biological sample detection method based on a continuously adjustable biological sample holder. The biological sample holder consists of two vertically aligned high-density polyethylene sheets (3, 4) having the same size and made of the same material, a high-density high-elasticity circular O-ring (3) in the middle between the two high-density polyethylene sheets, and M6 screws (1) for fastening and adjusting at four corners of the two high-density polyethylene sheets (3, 4). A biological sample with which the biological sample holder is filled is detected by using terahertz waves. Specific information about the biological sample of different thicknesses is tested by adjusting four M6 screws (1). The whole operation process is simple, easy and efficient. The thickness of a biological sample can be continuously adjusted, such that the probability of the biological sample being polluted is greatly reduced.
