Step 1
To atomise the substance
Answer
In atomic absorption spectroscopy (AAS), the flame serves the crucial purpose of atomising the substance. This process involves converting the sample into free atoms, which are essential for the absorption measurements. The flame provides the necessary energy to break molecular bonds, allowing atoms to enter the gaseous phase before they are analyzed for their absorption characteristics.
