Product Description GD-4530F Aas Flame Atomic Absorption Spectrophotometer with Computer and PrinteBasic structure Basic structure of atomic absorption spectrometer1. Light source: produces light with characteristic wavelengths of the analyzed elements. The common ones are hollow cathode lamp (HCL), stepless discharge lamp (EDL) and ultralight (UltrAA Lamp).2. Atomizer: convert the analyzed elements in the sample into free atoms in proportion. The energy required is usually heating. Commonly used methods are air-acetylene, nitrous oxide-acetylene flame and electric heating. Atomized atoms absorb light.3. Optical system: guide the light into the atomic vapor and guide the outgoing light into the monochromator.4. Monochromator: Separate the characteristic wavelength of the specific analyzed element produced by the element lamp from other non-characteristic wavelengths.5. Detector: A photosensitive detector (usually a photomultiplier tube) accurately measures the light intensity and converts it into an electrical signal6. Electronic circuit: converts the corresponding value of the detector into a useful analytical measurement value.Main Technical Features1. Completely controlled by PC, can flexibly select the flame and graphite furnace atomizer (optional);2. Eight light stands can be changed automatically and preheat the eight element lights meantime as well as optimize the working condition of the hollow cathode lamp;3. Position adjusting: the best height of the flame burner and can automatically set the front and rear positions;4. Fully automatically wavelength scanning and peak searching;5. Completely safety chains protection equipment: the function of warning and automatic safety protection towards the wrong burner, leakage of the gas, under voltage of air and the abnormal flameout;6. lamp and self-absorption background regulation;7. Data processing: super strong database, possesses more than 500 data self-storage and cut-off storage function, can store the analyzed result with the form of EXCEL and the testing method and the result can be randomly called;8. Measuring method: flame absorption method and emission method;9. Result printing: parameter printing, data result printing and diagram printing; Product ParametersTechnical Specifications of 4530F Atomic Absorption SpectrophotometerWavelength range190 - 900nmSpectral bandwidthCan automatically change between 0.1nm, 0.2nm, 0.4nm, 1.0nm and 2.0nmAccuracy of the wavelength±0.15nmReceptivity of the wavelength≤0.04nmBase line stability≤0.002A/30min (Cu)Characteristic viscosity0.02μg/ml/1% (Cu)Checking limit0.004μg/ml (Cu)Preciseness0.5%Grating1800 lines/mmInflamerAll-metal titanium burnerAtomizerEffective glass atomizerLamp standEight lampsD2 background correction abilityWhen the background is 1 A, the background ability should be deducted not less than 50 timesFlame system of atomic absorption spectrometerAcetylene air burner100mm100mm100mm100mm100mm(Cu) Characteristic viscosity(Cu) Characteristic viscosityRelated standard deviation of the accuracy≤0.5%(Cu, absorbance>0.8A) (detection limit Cu≤0.008μg/ml)Safety systemCan automatically cut off the gas when the pressure is not enough, the power is off, flameProcess of Flame Atomic Absorption Spectrometer1. Radiation from the specific light source is focused on the atomic vapor in the flame. 2. The radiation then enters a monochromator, which isolates the line of interest.3. The light is then measured by a photomultiplier tube (detector). 4. The signal is then processed and the computer system prints the output on screen. Warranty1.1 year.2.Within warranty periods, GOLD will supply the spare parts for the system for free if the product has self-quality problem. We also supply free maintenance in this period. If buyer require regular maintenance services, we can supply after signing agreement.3.After warranty periods, GOLD guarantee to supply the spare parts with competitive price in at least 20 years;4.In warranty period, if there are any quality problem, GOLD will be responsible, the premise is that the problem is not caused by personal factor.Detailed PhotosContact usIf you are interested in our Aas Flame Atomic Absorption Spectrophotometer with Computer and Printer product or have any questions, please feel free to contact us.
