Sample denudation pool for laser denudation inductively coupled plasma mass spectrometer

The invention discloses a sample denudation pool for a laser denudation inductively coupled plasma mass spectrometer, which comprises a cylinder, a left cone and a right cone, wherein a rhombic grooveis formed in the middle of the upper surface of the cylinder; the bottom of the rhombic groove is a bottom plate fixedly connected with the cylinder, the side wall of the cylinder is provided with anair inlet and an air outlet which are symmetrical, the air inlet and the air outlet are both communicated with the rhombic groove, the left cone is located at the outlet end of the air inlet in the rhombic groove, and the right cone is located at the inlet end of the air outlet in the rhombic groove. The sample denudation pool provided by the invention is filled into a sample pool carried by an existing instrument company, so that the volume of the denudation pool used at the present stage is reduced. The problems of slow mass spectrum signal response, low flushing efficiency and remarkable position effect of a curren
