SUMMARY OF METHOD
The High Range Dissolved Oxygen AccuVac Ampul contains reagent
that is vacuum sealed in a 12-mL ampul. When the AccuVac ampul is
broken open in a sample containing dissolved oxygen, it forms a yellow
color which turns purple. The purple color development is proportional
to the concentration of dissolved oxygen.
