Atomisers:

The reason of atomiser is to gives a representative portion of the analyte in the optical path and converts it into free neutral ground state atoms. Within atomic absorption spectrophotometry, a flames and furnaces which generate a temperature in the range of 1500 to 3000 ºC are the most general methods of atomisation. Two common categories of atomisers used for producing atomic species within the vapour phase are flame atomisers and electrothermal atomisers. Now let us learn about flame atomisers. You will learn about electrothermal alone use in flameless atomic absorption spectrum.
