The automatic micro area sampling instrument, which is observed under the microscope, uses the precise movement of the electric platform to realize the sampling and collection process, and has the function of vacuum adsorption.Different types of microscopes, such as stereoscopic, inverted and upright microscopes, are selected according to the specific requirements.It can be widely used in various fields, and can be configured according to the specific needs of different accessories, saving costs, highlighting the use of performance.For example, a stereomicroscope with a mobile platform can be used to take rock samples, which is convenient for the movement of stalagmite samples. The following is the image of the program controlled automatic XYZ three-dimensional translation stage and the program controlled automatic XYZ three-dimensional translation stage. In this way, the sampling instrument adopts the vertical drilling sampling method, and the drilling needle can be stably fixed on the top of the host machine, in a horizontal position with the vacuum collection part. The vacuum suction head can be tilted and placed at the same position or close to the drill needle to collect samples while drilling.

Microdrill sampler is a kind of micro sampling equipment for carbonate, zircon and other rocks and minerals. The size of the sample determines the size of the bit to be used. The size and number of boreholes used depends on the needs analysis. People who often do carbonate research know that the analysis of stable isotopes C and O requires about 10 micrograms of sample, which can meet the requirements of high-quality isotope mass spectrometry analysis. This number can be obtained by using a 100 micron diameter drill bit, drilling 20 microns into the sample and drilling about 25 to 30 holes. Using a square plate sample, the same 100 micron drill bit, in a 600 micron deep hole, will produce enough samples.For small bits, such as 8 microns in diameter, a larger number can be obtained by drilling 20 microns into thin slices. Of course, these results assume that 100% of the samples are collected by pipette. Other types of sample analysis, such as ICP, will have different sample requirements, and the number of holes will also be changed accordingly. According to the specific needs, the size of drill bit and the moving accuracy will be confirmed..
