Limitations of flame photometry, Chemistry

Limitations of flame photometry:

The limitations of the techniques involve the following.

The low temperature of the natural gas and air flame limits a method to simply ionized metals. The method is selective by restricted towards easily excitable alkali and alkaline earth metals.
The low flame temperatures render this method susceptible to certain drawback, most of them related to interference and the stability of the flame and aspiration conditions.
That will tells us nothing about the molecular form of the metal within the original sample.
Just liquid samples could be used. In some cases, lengthy steps are essential to prepare liquid samples.
