The temperature of graphite furnace atomic absorption spectrometry can vary depending on the specific method and equipment used.
7 Key Points About the Temperature of Graphite Furnace Atomic Absorption Spectrometry
1. Pyrolytic Process Temperature Range
In general, the temperature rises to a range of 400 to 800 degrees Celsius during the pyrolytic process.
2. Purpose of Initial Heating
This initial heating step is used to remove matrix components and high boiling volatile compounds from the sample.
3. Rapid Temperature Increase
After this initial heating step, the temperature is rapidly increased up to 3000 degrees Celsius.
4. Importance of High Temperature
This high temperature is necessary to form atomic vapor, which is essential for the atomic absorption spectrometry process.
5. Ideal Starting Material
The starting material for graphitization should ideally consist solely of carbon atoms with negligible impurities.
6. Pre-Carbonization Step
In cases where the starting material contains organic matter of unidentified composition or has a large amount of impurities, it is advised to pre-carbonize the sample in a low temperature hot wall furnace at up to 1100 degrees Celsius.
7. High Temperature Graphite Furnaces
Graphite tube furnaces are commonly used in high temperature applications, including graphitization. These furnaces can operate at temperatures up to 3000 degrees Celsius and are suitable for research and development purposes.
