Abstract

The invention discloses an adjustable photoelectric double-pulse laser-induced breakdown spectrometer which comprises a clamping plate, a moving platform, a moving concentric-square-shaped sliding block, a linear sliding rail, a detection cylinder, a focusing lens, a machine shell, a detection pipe, a pulse laser, an electronic computer, a monochromator, a data acquisition unit, a position-adjustable supporting frame structure, a cooling fan structure capable of dissipating heat and a sample collecting and filtering tank structure. The clamping plates are transversely connected to the upper portion and the lower portion of the left side of the movable platform through bolts. The moving platform is longitudinally connected to the inner side between the moving concentric-square-shaped sliding blocks through bolts. Through the arrangement of the movable seat, the movable shaft, the flat head lining rod, the supporting bottom frame, the connecting seat and the electric push rod, position adjustment according to detection requirements is facilitated, and the detection operation requirements are met.

Description

technical field [0001] The invention belongs to the technical field of applied spectroscopy, in particular to an adjustable photoelectric double-pulse laser-induced breakdown spectrometer. Background technique [0002] Laser-induced breakdown spectroscopy (LIBS) technology is to focus a high-energy pulsed laser on the surface of a certain substance to be analyzed to generate high-temperature plasma, and a small amount of material peeled off by the laser is in the high-temperature plasma. Atomized and ionized, and emits the characteristic spectral radiation of atoms or ions. The analysis of the element concentration (or content) in the sample is realized by analyzing the spectral intensity. This technology has the characteristics of no need for complicated sample preparation process, fast, industrial online and long-distance analysis. However, the analytical sensitivity of the single-pulse LIBS technique is not high, which restricts its application in the field of rapid ana...
