To avoid the volatilization of mercury vapour during molten sample from influenceing test result, experiment is carried out molten using closed high temperature pressure resolution method
Sample, that is, place a sample into polytetrafluoroethyltank tank, add nitric acid and hydrochloric acid, tightened with stainless steel outer sleeve, in high temperature and closed appearance
Sample is dissolved in device, the mercury of various forms in sample is carried out mercury content analysis after being completely converted into ionic mercury.
This measuring method is needed through multiple processes such as over sampling, dissolving, measurement, analysis, process is various, content is complicated,
Test period is long, the probability of error is big, can not meet that the production and living quickly tested require that.
The content of the invention
The present invention is directed to prior art defect, there is provided a kind of portable mercury content detecting instrument.
What the present invention was realized in：A kind of portable mercury content detecting instrument, including tester fuselage, in tester machine

Transmitting apparatus, the X ray excited are projected by measuring head.
A kind of portable mercury content detecting instrument as described above, wherein, described excitation of X-rays device uses
The special miniature X ray light pipe Mini-X-OEM of AMPTEK-OEM.
A kind of portable mercury content detecting instrument as described above, wherein, portable mercury content detecting instrument also includes visiting
Device is surveyed, the detector is used to detect X-ray energy spectrum, and the data output end of the detector is connected with Portable tablet personal computer, and this is just
The formula tablet personal computer of taking is arranged on tablet personal computer placement platform.
A kind of portable mercury content detecting instrument as described above, wherein, described data-interface is USB interface.
A kind of portable mercury content detecting instrument as described above, wherein, the thick Ni of 0.1mm are set in measuring head front end
Optical filter, using rhodium target X-ray tube.
The present invention remarkable result be：The detecting instrument of the application can be tested directly sample, without passing through
Sample, dissolve, measuring, analyzing complicated process, and test result can save the testing time with real-time display.Additionally by X
Ray is detected, and accuracy rate is higher than the accuracy rate of re-test after being dissolved in conventional art.
Instrument uses contact measurement mode, and after starting measurement, X ray exit portal has X ray to send, if X ray is inclined
From test position, it is possible to artificial into radiation, inductive pick-up is devised in instrument internal for this.It is true that software reads the signal
It is fixed effectively just to allow to start measurement, once instrument leaves detected sample, high voltage power supply is automatically shut down, avoids radiation leakage, from
And it ensure that the security of operation.
What is given off from X-ray tube is continuous X-rays, and this continuous X-rays become background through sample scattering, often make essence
Density and detection limit reduce, characteristic X-ray coherent scattering (Rayleigh scattering) and incoherent scattering as caused by X-ray tube in addition
(Compton scattering) can become the analytical line weak peak that interference occurs in its vicinity.To solve the influence of ambient interferences, instrument development
During employ the thick Ni optical filters of 0.1mm, the influence of impurity lines, simultaneous selection rhodium target X-ray tube, RhK α, K β can be eliminated
Launching efficiency Deng characteristic X-ray is high, and the spectral line of the elements such as lead, arsenic is not disturbed, and the background of its continuous X-rays is low, can
Effectively reduce the interference of background.
