Acid Digestion is a process of preparing analytical samples for analysis.
Acid Digestion Pressure Vessels: -
By combining the unique chemical inertness of polytetrafluoroethylene (Teflon) with the advantages of a sealed pressure vessel, they offer a rapid procedure for sample dissolution or digestion that has several important advantages over more traditional methods of sample preparation. By providing a convenient means for holding strong mineral acids or alkalis at temperatures well above normal boiling points, digestion bombs will: -
- Accelerate digestions which otherwise would proceed slowly if conducted in an open container at atmospheric pressure.
- Permit the use of strong acids, such as hydrofluoric acid or aqua regia, which will attack most other conventional containers.
- Dissolve analytical samples without losing trace elements and without adding unwanted contaminants from the container itself.
- Generate a vigorous chemical action that is a great time saver in analytical procedures.
- Obtain complete digestion or dissolution of samples that react slowly or incompletely when treated by other methods.
Chemists who have worked with sealed glass tubes and other cumbersome digestion devices will recognize the attractiveness of these convenient digestion vessels.
