Abstract
A method of dispensing an analytic reference material includes providing a dispensing device including an ampoule having at least two storage lumens extending axially along the length of an ampoule body, an analytic reference material subunit in each of the storage lumens, distal gaskets sealing the analytic reference material subunits from a distal end of the ampoule, and an outlet lumen. The method also includes providing a plunger assembly coupled to a proximal end of the ampoule, the plunger assembly in communication with the storage lumens and depressing the plunger assembly to force the distal gaskets into gasket seats in the dispensing device and expelling the analytic reference material subunits from the storage lumens via the outlet lumen to form the analytic reference material.
