Why Graphite Furnace Atomization gives higher sensitivity
The graphite furnace can be programmed for temperature increase at a very high rate of around 2000 0 C and reaches the final temperature of around 3000 0 C in a matter of 2 seconds and thereafter you can optimize the observation time to about 2 minutes In contrast the temperatures of flames are usually lower Air –Acetylene flames
