Advantages and Disadvantages of Flame Photometer

The flame photometer is an instrument used to detect sodium, calcium, potassium, and lithium ions; it depends on the intensity of emitted light.
The advantages of flame photometer:

  • This is a rapid, suitable, selective and responsive analysis. 
  • It’s a simple and economical method of analysis. 
  • Used in the qualitative and quantitative analysis of metal ions.
  • The elements that are rarely analyzed in this method can be determined.
  • Very low concentrations of metal ions can also be determined from the sample.
The disadvantages of flame photometer:
Despite several advantages, there are some disadvantages to this analysis technique, let’s check it.
  • The only liquid sample can be analyzed through this technique.
  • In some cases, sample preparation is longer.
  • This method does not give information regarding the molecular structure of the metal ion, which is present in the sample.
  • Each and every metal atom cannot determine by flame photometry.
  • The concentration of the metal ion cannot be accurately measured by this technique.
