Graphite furnace employs temperature programming to produce elemental vapor.
The program begins by raising the furnace temperature to initiate ______________, where water is removed from the sample.
Next, the temperature of the furnace is then raised to begin the ________________ process, where organic material is removed.
The temperature of the furnace is raised again to ________________ the sample, creating the elemental vapor required for spectroscopy.

a) baking; desiccation; atomize

b) drying; desiccation; fragment

c) baking; atomize; desiccation

d) drying; charring; atomize

e) drying; atomize; charring

Answer:

(d) drying; charring; atomize

Explanation:

In the first part of the question, water was taken out of the sample by increasing the temperature of the furnace. Therefore, the process is known as drying.

In the second part, the organic components of the sample were taken out by a further increase in the furnace temperature. This process is known as charring.

In the last part, vapor was produced by a further increase in the furnace temperature. The action word is 'atomize'.
