Abstract

The invention discloses a sample injection boat of a direct mercury analyzer, belonging to the technical field of element analysis equipment. The sample injection boat is composed of a boat body and acover, wherein the boat body is composed of a sample chamber, separation blades and a slide rail; the sample chamber is a trapezoidal long groove arranged in the boat body, and the upper part of thesample chamber is provided with an opening; downwardly recessed separation blade grooves are arranged in the sample chamber at an equal distance; the slide rail is a semi-circular slide groove arranged at the edge of the opening of the sample chamber; the separation blades are inserted into the separation blade grooves in the sample chamber, the shapes of the separation blades are matched with theshape of the sample chamber, and the upper end surfaces of the separation blades are is flush with the upper part of the sample chamber; the cover is composed of a protective cover and a cover handle; and a sealing coating is arranged on the bottom surface of the protective cover. The sample injection boat of the invention ensures that a sample does not scatter and topple over during the movementof the sample introduction boat, so the problem of wasting of the sample or contamination of the direct mercury analyzer is overcome; and the purpose that a same solution is different in quantity indifferent stages is achieved by controlling volume fractions, so gradient changes of a solution are realized; and the time for preparing standard solutions of different concentrations is saved, so work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of elemental analysis equipment, in particular to a sample boat for a direct mercury measuring instrument. Background technique [0002] The sample injector introduces the sample to be tested into the absorption cell, and volatilizes into gas through heating, and the light passing through the absorption cell is absorbed and reduced, so as to determine the content of the components in the sample. The traditional method of measuring mercury requires sample pretreatment, and the volatility of mercury will directly lead to uncertain results, causing destructive pollution to the optical measurement cell of the instrument, and mercury will pollute the laboratory environment and human health. The direct mercury measuring instrument does not need to pre-treat the sample, the sample will directly enter the absorption pool of the instrument for thermal decomposition and gold amalgam reaction, keeping the laboratory en...
