[0022] Example 1
[0023] The multifunctional sample chamber of this embodiment that can be used for laser-induced breakdown spectroscopy analysis has a structure as attached figure 1 And figure 2 As shown, a closed chamber 7 that can be opened from the top of the chamber shell, a quartz focusing lens 1 arranged on the top of the chamber shell, a sample tray 3 installed on a rotatable lifting column 8 located in the center of the chamber bottom, and A signal collection device 9 connected to an external detector on the wall of the chamber is composed of. The sample plate and the plate of the rotating lifting column platform 8 are fixedly arranged together by a buckle, and the rotating lifting column platform is driven to move by a stepping motor. The sample tray is designed with 8 symmetrically arranged circular pit sample cells 2, which are located on the same diameter circle in the surface of the sample tray. When the sample tray rotates, it can be turned directly below the qu...
