Drawbacks:

Flame atomisation, thus, has following drawbacks.

i) Only about 10 percent of the nebulised sample reaches the flame and it is then additionally diluted through the fuel and oxidant gases so in which test material has extremely small concentration in the flame.

ii) A minimum sample volume of 0.5-1.0 mL is required to provide a reliable measurement.

iii) Viscous samples like as blood, serum, oils etc needs dilution along with a solvent. In order to prevent such problems, nonflame methods including electrical heating have been established for atomisation.
