Sample application device for strontium and lead detection of thermal ionization isotope mass spectrometry

Abstract

The invention discloses a sample application device for strontium and lead detection in thermal ionization isotope mass spectrometry. The sample application device comprises a base, the top of the base is fixedly connected with a processing table, and the top of the processing table is fixedly connected with a fixed vertical plate. According to the invention, a sample application operation mechanism is placed at the top of the processing table, the positions of a first sample application assembly and a second sample application assembly are fixed through a connecting lead screw, and therefore the whole mechanism can be rapidly transferred and disassembled to be suitable for multiple machines; a sampling tube is inserted into a positioning hole to be placed, a thin-layer plate is placed between two control clamping plates, a rotating handle of the control screw rod is rotated to fix the position of the thin-layer plate by the control clamping plates, according to the position of the sampling tube, when a positioner moves to a sampling head and is aligned with the sampling tube, a control sliding plate is pushed to drive the sampling tube to move, and an electric push rod further performs sample application; and therefore, materials with different densities can be subjected to sample application detection at a time while the positions of the materials are accurately positioned.

Description

technical field [0001] The invention is used in the technical field of spotting, and in particular relates to a spotting device for detecting strontium and lead in thermal ionization isotope mass spectrometry. Background technique [0002] Lead is a metal chemical element. Metal lead is a heavy non-ferrous metal material with corrosion resistance. Lead has the advantages of low melting point, high corrosion resistance, difficult penetration of X-rays and γ-rays, and good plasticity. It is often processed into Plates and pipes are widely used in industrial sectors such as chemical industry, cables, batteries and radiation protection. Strontium is a silvery-white alkaline earth metal with yellow luster. It is the least abundant element among alkaline earth metals (except beryllium). It is used in the manufacture of alloys, photoelectric cells, and analytical chemical reagents, pyrotechnics, etc. Solid phase extraction is a sample pretreatment technology developed in recent y...

AI Technical Summary

Problems solved by technology

During the preparation of the sample solution, different spotting equipment, spotting volume, and spotting methods are all factors that cause errors.

[0004] In the process of spotting samples of strontium and lead currently on the market, usually only one material can be sampled, and the position of the material cannot be accurately located. The machines are all modified, the production cost is high, and the waste of time is long. Therefore, it is impossible to solve the problem of multiple spotting, and it is also impossible to complete the rapid transfer and disassembly of the whole mechanism to apply to multiple machines.
