    What is AAS :- •  AAS abbreviation is atomic absorption spectrometer. •  AAS is a machine used to detect the element such as metal and minerals. •  It measures different types of matrix (food, pharmaceutical, water chemical and etc.) Principle of AAS :- •  AAS works based on Beer- Lambert's  law. •  It says that absorption is directly proportional the path length and concentration of the solution. •  In AAS we can analyze elements in both the way absorption as well as emission. AAS Instrumentation:- •  Air compressor  (for air) •  Acetylene (fuel gas) •  Nitrous oxide (high temperature) •  HVG (for lower concentration( ppb ) •  Exhaust •  Nebulizer  for the conversion of liquid to aerosol •  Bruner  To ignite flame (normal flame 10 cm high flame 05 cm) aerosol converts to atomization. •  Lamps  To emit a ...
