◇ Adopt and ask for the flame law with exclusive female technology and antithetical couplet of the hydrogenation law to use,has increased elements of analyzing,have widened and analyzed the range
◇ Adopt it take the empty than function not adjustable not flexible,it determine element not different choose different to take empty than,improve the sensitivity and stability of the instrument
◇ Adopt and flow and enter kind in succession,the high total mark of the peak,improve the sensitivity of testing
◇ Adopt the codes core not empty negative pole light high strength,it to choose is best to it is be empty to take automatically than,strengthen the luminous intensity and stability of the light source
◇ Adopt the double layers and mix the atomized room in advance, improve the stability of testing
◇ Adopt and mix and reflect the module and antithetical couplet of the mixing chamber in advance multi-functionally and use technology,purpose to achieve the multistage air liquid and separate
◇ Adopt the double-deck multicipital quartz atomization device,reduce the fluorescence to kill suddenly,strengthen atomization efficiency,improve the sensitivity of the instrument
◇ Adopt single dish and strengthen the function,make the intensity of test fluorescence strengthen,stability increase
