Abstract:
Based on the objective law that the nickel ion beam can wantonly changed. NGCAAS-Ⅱis a new designed circuit used for clinical element microdetecuon on Atomic Absorption Spectrophotometer (AAS).It effectirely lessons the thermowidening,self- absorption of spectral line and interference of ion line,thus comprehensively improves the practical value of AAS.Its energy is 100 times bigger than the energy of square circuit. Besides,if abtains better signal-to-noise ratio and anti-interference ability.Farther more, it has better sensibility and background-correction.
