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)drying;charring;atomize
D)drying;atomize;charring
E)baking;atomize;desiccation

Quizplus · Accepted Answer

The first step of the temperature program is drying the sample to remove any surface water, followed by charring to remove organic material. The final step is to atomize the sample creating the elemental vapor needed for spectroscopy. This process is specific to the graphite furnace technique. Choice C correctly identifies each step in the process.
