Abstract

The invention belongs to a detection device, and especially relates to a portable mercury content detection device. The portable mercury content detection device comprises a tester body, a test head is arranged at the forefront end of the tester body, a handle is arranged under the tester body, the handle is provided with a trigger, a support is arranged at the front end of the handle under the tester body, a tablet computer storage platform is arranged on the rear part of the tester body, and the tester body is provided with a data interface. The detection device can directly test a sample without complicated sampling, dissolving, measuring or analyzing processes, can display a test result in real time, and saves the test time. The accuracy of the detection device using X-ray to detect ishigher than the accuracy of traditional technologies characterized by performing test after dissolving.

Description

technical field [0001] The invention belongs to detection instruments, in particular to a portable mercury content detection instrument. Background technique [0002] Traditional mercury content analysis methods require pretreatment of samples with chemical reagents such as acids or bases. Traditionally, the mercury content in scrap metals is mainly measured by cold atomic fluorescence spectrometry. [0003] The cold atomic fluorescence spectrometry requires pre-dissolution of the sample. Since the sample is a metal part, it is difficult to dissolve the sample. In order to avoid the volatilization of mercury vapor during the sample dissolution process and affect the test results, the test uses a closed high-temperature pressure digestion method to dissolve the sample. That is to say, put the sample into a polytetrafluoroethylene tank, add nitric acid and hydrochloric acid, tighten it with a stainless steel jacket, dissolve the sample at high temperature and in a closed cont...
