Abstract
The invention discloses a laser-induced breakdown spectrometer for multi-sample detection, which comprises a sample adding chamber, supporting legs, an observation window, a sample placing and takingcover, a fixed shaft, a rotary detection disc, a placement groove, a detection chamber, a focusing lens, a laser head, a receiving coupling lens, an optical fiber chamber, a spectrograph body, a computer, a self-return type sample pressing and cutting blade structure, an adjustable sample surface cleaning hair structure and a post-detection sample collecting and filtering protective box structure,wherein supporting legs are longitudinally connected to the four corners of the bottom of the sample adding chamber through bolts, the observation window is embedded in an observation opening in theright side of the sample adding chamber, and the sample placing and taking cover is connected to a left placing opening of the sample adding chamber through a movable bolt. Through arrangement of a self-return pressing seat, a U-shaped lining seat, a cutting table, a self-return spring, a cutting motor and a cutting blade body, cutting of a to-be-detected sample is facilitated, so that the detection convenience is guaranteed, and the detection requirement is met.
Description
technical field [0001] The invention belongs to the technical field of laser-induced breakdown spectroscopy detection, in particular to a laser-induced breakdown spectrometer for multi-sample detection. Background technique [0002] Laser-induced breakdown spectroscopy (LIBS for short) is a new technology that uses high-energy pulsed lasers to interact with materials to generate plasma emission spectra and perform elemental analysis. Compared with traditional spectral measurement techniques, LIBS technology It has many advantages: (1) Analysis of multiple elements can be carried out at the same time; (2) Under non-destructive or non-contact conditions, it can truly achieve rapid on-site analysis, no need for sample pretreatment, convenient analysis, and no re-contamination of research objects The probability is small; (3) The measurement object is almost unlimited, which can be solid, liquid, gas, or high hardness and insoluble substances; (4) Continuous monitoring can be re...
