![]() ≤0.5%(Cu, absorbance>0.8A) (detection limit Cu≤0.008μg/ml)Ĭan automatically cut off the gas when the pressure is not enough, the power is off, flameout and unconformity of the burner. Related Standard Deviation of the Accuracy Hollow cathode lamp(Ag, Au, Ba, Ca, Cd, Cr ,Fe, Hg ,K, Li, Mg,Mn, Na, Ni, Pb, Zn, Sb,etc) When the background is 1 A, the background ability should be deducted not less than 50 times self absorption background deduction method Data processing: more than 500 data self-storage and cut-off storage, the analyzed result is stored in EXCEL format. of a specific wavelength from a hollow cathode lamp (HCL), passing through the flame. A hollow-cathode lamp (HCL) is type of cold cathode lamp used in physics and chemistry as a spectral line source and as a frequency tuner for light sources. ![]() Most instruments today use a hollow cathode lamp that is specific to each element being analyzed to emit a very narrow bandwidth of UV or visible radiation into the instrument for detection. Direct Aspiration or Flame Atomic Absorption Spectrometry (FAAS). The Hollow cathode Lamp is made with an element (metal) as the cathode encased in a bulb with a low pressure inert gas. Deuterium lamp and self-absorption background calibration.Ĩ.Measuring method: flame absorption method and emission method.ĩ.Result printing: parameter, data result and diagram.ġ0. Practical Multi-Element HollowCathode Lamps for AtomicAbsorption SpectrometryApplication NoteAtomic AbsorptionAuthorsIntroductionDouglas ShraderMulti-element. FAAS, a source of pure light is needed to excite the analytes without causing excessive instrumental noise. Tag Archives: atomic spectroscopy Hollow Cathode Lamp Graphite Furnace Cross-Sectional Profile of Flame in FAAS Absorbance vs. Complete safety chains protection equipment: warning and automatic safety protection for the wrong burner connection, leakage of the gas, under voltage of air and the abnormal flameout.ħ. Agilent multi element hollow cathode lamps have cathode compositions that feature up to 6 elements in combination. Fully automated wavelength scanning and peak searching.Ħ. The hollow cathode lamp (HCL) uses a cathode made of the element of interest with a low internal pressure of an inert gas. Eight light stands can be changed automatically and preheat the eight lights meantime as well as optimize the working condition of the hollow cathode lamp.Ĥ. Position adjusting: the flame burner can be set on the best position automatically.ĥ. The AA-6880 can simultaneously light any two hollow cathode lamps. Integrated floated optical platform design improves the optical system shock resistance stable.ģ. Completely controlled by PC, can flexibly select the flame and graphite furnace atomizer (optional).Ģ.
