Abstract

A dispensing device is disclosed having an ampoule with at least four storage lumens extending axially along the length of an ampoule body, a mixing tip coupled to a distal end of the storage lumens, the mixing tip having at least four gasket seats formed therein, each gasket seat corresponding to one of the storage lumens, and an outlet lumen in fluid communication with the storage lumens.

Claims

1. A device for dispensing liquid material, comprising:

an ampoule having at least four storage lumens extending axially along the length of an ampoule body, the storage lumens having a diameter in the range of about 0.01 inches to about 0.25 inches;

a mixing tip coupled to a distal end of the storage lumens, the mixing tip having at least four gasket seats formed therein, each gasket seat corresponding to one of the storage lumens;

an outlet lumen in fluid communication with the storage lumens via the mixing tip; and

an analytic reference material subunit provided in at least two of the storage lumens, wherein each of the storage lumens has a proximal gasket sealing the analytic reference material from a proximal end of the ampoule and a distal gasket sealing the analytic reference material from a distal end of the ampoule and wherein the proximal gasket and the distal gasket are spherical.

2. The device of claim 1, wherein a mixing channel in the mixing tip couples each of the storage lumens to the outlet lumen.

3. The device of claim 1 further comprising a plunger assembly coupled to a proximal end of the ampoule in communication with the storage lumens.

4. The device of claim 3, wherein the plunger assembly comprises at least four pistons, the pistons associated with corresponding storage lumens and receivable therein.

5. The device of claim 3, wherein the plunger assembly comprises a working fluid dispensing apparatus in fluid communication with the storage lumens.

6. The device of claim 1, wherein each of the storage lumens has a diameter equal to the others.

7. The device of claim 1, wherein each of the storage lumens are equidistant from the outlet lumen.

8. The device of claim 1, wherein at least one analytic reference material subunit is chemically incompatible with at least one other analytic reference material subunit.

9. The device of claim 1, wherein the distal gasket has a diameter larger than the diameter of its corresponding storage lumen.

10. The device of claim 1, wherein the proximal gasket and the distal gasket are constructed of polytetrafluoroethylene.

11. The device of claim 1, wherein the ampoule has at least twelve storage lumens extending axially along the length of the ampoule body, the mixing tip having at least twelve gasket seats, each gasket seat corresponding to one of the twelve storage lumens.

12. The device of claim 11, wherein each of the twelve storage lumens has a diameter equal to the others.

13. A device for dispensing liquid material, comprising:

an ampoule having at least four storage lumens having a diameter from about 0.01 inches to about 0.25 inches formed therein extending axially along the length of an ampoule body;

a mixing tip coupled to a distal end of the ampoule body, the mixing tip having a mixing channel and a plurality of gasket seats, each gasket seat aligned with one of the storage lumens;

a plunger assembly coupled to a proximal end of the ampoule, the plunger assembly having at least four pistons, the pistons associated with corresponding storage lumens and receivable therein; and

an analytic reference material subunit provided in each of the storage lumens, the analytic reference material subunit sealed between a proximal gasket and a distal gasket slidably disposed within the storage lumens,

wherein when the distal gasket is seated in the gasket seat, the mixing channel fluidly connects the analytic reference material subunits of the storage lumens to the outlet lumen.

14. The device of claim 13, further comprising a dead space in the storage lumens intermediate the proximal gasket and the storage lumen'"'"'s corresponding piston and a dead space in the storage lumens intermediate the distal gasket and the distal gasket seat.

15. The device of claim 13, wherein a volume between the outlet lumen and each storage lumen is identical.

16. The device of claim 13, wherein the storage lumens are equidistant from the outlet lumen.
