Abstract

The invention relates to an automatic sample preparation apparatus and an optically stimulated luminescence dating instrument, which belong to the field of electronic and electrical equipment design and production as well as geology. The automatic sample preparation apparatus is characterized in that a primary election module is used for performing preliminary treatment of a sample and separatingthe sample to obtain the sample with appropriate particles, the sample is conveyed to a sample processing module, and is subjected to further processing treatment; and finally the sample is sent to acareful selection module for careful selection and separation to obtain the sample suitable for detection. The automatic sample preparation apparatus has the advantages of simple and controllable process, and high screening efficiency; the optically stimulated luminescence dating instrument comprises the above automatic sample preparation apparatus, the sample can be prepared by the automatic sample preparation apparatus, and the sample is tested through a measurement module.

Description

technical field [0001] The invention relates to the design and production technology of electronic and electrical equipment and the fields of geology and archaeology, and in particular to an automatic sample preparation device and an optical luminescence dating instrument. Background technique [0002] Optically Stimulated Luminescence (OSL) is a dating method widely used in Quaternary geology and environment, archaeology, active structure, paleoseismic research, etc. Mineral particles in sediments (mainly quartz or feldspar that are meaningful for OSL dating) are buried and no longer see light, and at the same time continuously receive α produced by the decay of radioactive substances such as U, Th, and K in the surrounding environment. , β, γ, and cosmic rays, etc., cause the electrons in the crystal to ionize and leave the crystal to form free electrons, which are then trapped by "electron" traps formed by lattice defects caused by impurity atoms or other factors in the c...
