Methods for Composition Analysis and Measuring Instruments

A) Methods based on atomic or molecular or crystalline characteristics of the matter:

  • Absorption Spectroscopy
  • Emission Spectroscopy
  • Mass Spectroscopy
  • X-Ray Diffraction Method

B) Methods based on measurement of the following physical characteristics of the matter:

  • Thermal Conductivity
  • Electrolytic Conductivity
  • Combustibility
  • Magnetic Susceptibility(Oxygen analyser)
  • Physical Absorption Characteristics(Chromatography) 
  • Refractive Index
  • Density or Specific Gravity
  • Viscosity
  • Acidity or Alkalinity(pH)
