Instrument Details
Instrument/Facility Name: Atomic Absorption Spectro-Photometer
Make                                   : Electronics Corporation of India Ltd
Model                                  : AAS1411
Specification   :Fully automated PC controlled Atomic Absorption Spectrophotometer equipped with the features like automatic wavelength selection, lamp current and slit with selection, automatic setting of all parameters, Fully advanced design compatible for working in ppm level detection range in flame mode.

Click to ViewThe AAS can work on complete range of wavelength i.e. 190-900 nm. The details of specifications are as follow: Silt width: continuously variable from 0 to 2.0 nm; Detector: PMT detector; Flame mode: coded, Titanium 100 nm, single slot air/acetylene and 50 mm nitrous oxide/acetylene burner heads. Fully pre-set flow with computer controlled gas box for monitoring and control of fuel/oxidant ratio, automatic flame ignition and extinguish etc. Automatic input of additional gases for organic solvent. Automatic change over air/acetylene to nitrous oxide/acetylene. Automated safety monitoring for fuel gas type, burner recognition and type, fuel and oxidant, liquid level waste vessel pressure and flow rate. Facility for auto shut down of gases in case of any abnormality.

  Working Principles
Click to ViewAtomic absorption spectroscopy is based on the principle that when a beam of electromagnetic radiation is passed through a substance, the radiation may either be absorbed or transmitted depending upon the wavelength of the radiation. The absorption of radiation would bring about an increase in the energy of the molecule. The energy gained by the molecule is directly proportional to the wavelength of radiation. The increase in the energy of the molecule leads to the electronic excitations where electrons jump to higher energy levels. A particular wavelength that a given molecule can absorb depends upon the changes in vibrational or rotational or electronic states.

  Applications
  User Instructions
The Atomic Absorption Spectrophotometer can be used for quantitative elemental analysis like Copper, Zinc, Iron, Manganese etc. by measuring the absorbance of a sample atomized in a flame. In case of any emergency while air-acetylene gas is on, immediately put off the Fuel switch and then turn the oxidant knob to off position. In case of nitrous oxide-acetylene flame is on, first change the oxidant knob from nitrous oxide to air then reduce the fuel flow with control knob of fuel flow meter and put off the fuel switch. Always switch on exhaust system when flame is on. After completing the analysis work, always ensure that the gas cylinder, compressor outlet is in closed position. Switch off the power supply. The user should contact at given address before bringing/sending the samples for analysis.
