The development of the technology such as Spectroscopy With Suspension-injection and application, the analysis means of solid sampling and the analysis ability of sample has been obtained greatly
Amplitude promotes.Wherein, ETV-ICP-MS because its capacity of resisting disturbance is relatively strong, linear dynamic range width and the energy of Simultaneous multi element analysis
Power, enjoys researcher to pay close attention in solid sampling spectral technique.
Although the spectral instrument of Direct solid sampling can use certain background correction technology to alleviate matrix interference shadow
Ring, but this kind of remedial technique, and the complicated substrate that solid sampling process is brought and spectral interference always limit ETV
Solid sampling development and application bottleneck problem.Atom trap capture is that a kind of very effective solid sampling matrix interference eliminates skill
Art, such as, utilize the survey hydrargyrum solid sample feeding device of gold amalgam principle, utilize tungsten filament to catch the survey cadmium solid sample feeding device of cadmium principle.On
The technology of stating utilizes spun gold/tungsten filament can capture atomic state hydrargyrum/cadmium at normal temperatures, and can the most effectively discharge hydrargyrum/cadmium, passes through
The capture of hydrargyrum/cadmium separates with matrix, can realize preenrichment and separate two targets with matrix, thus effectively alleviate matrix interference.
At present, there is not yet and utilize tungsten filament preenrichment zinc to eliminate atomic absorption spectrum matrix interference for atomic absorption spectroscopy
Report.
