Atomic Absorption Spectrophotometer (AAS) is for determining the concentration of a particular metal(element) in a sample. AAS can be used to analyze the concentration of over 62 different metals.
Light-source system | Hollow cathode lamp power supply: with adjustable current Deuterium Lamp power supply: with fixed current |
Optical system | Double beam total refection system, C-T type monochromator Flashing wavelength: 250nm |
Flame atomization system | Inter-changeable titanium alloy burner of 10cm and 5cm slits. Gas path is equipped with pressure indication, high precision voltage stabilizing flow adjustment, fast conversion of air and nitrous oxide, gas supply cut off, power cut off, prevention of flashback and logic interlock protection devices. |
Signal processing | Build-in microprocessor and LCD. Signal amplifying modes: absorptance, concentration, emission and emission concentration; Standard curves: linear regression, curve fitting and multi-point standard calibration. Average value, standard deviation, relative standard deviation and correlation coefficient can be worked out. Standard curves, atomic absorption peak diagram, spectrum outline sketch data as well as instrument parameters list and analytical reports can be displayed and printed out. |
