Parr Bomb Combustion

Parr Bomb Combustion is a preparative technique used to prepare samples for instrumental analysis.  This technique is commonly used to prepare samples for halogen and halide analysis by Ion Chromatography (IC).


Galbraith’s internal procedure for parr bomb combustion is G-55.  Click below to view a copy of the method summary:



A portion of sample is weighed into a combustion cup.  A combustion aid, such as benzoic acid or mineral oil may be added to improve combustion.  A known volume of absorber solution is placed in the bottom of the bomb.  The Parr Bomb is assembled and is charged to 30 ATM with pure oxygen.


When ignited, the sample is burned quantitatively and any covalent halogen is converted into the corresponding halide salt.  The halide and any native halide present in the sample are absorbed into the absorber solution.   The absorber solution is poured into a separate container and is then analyzed by IC.
