Abstract

The present disclosure is directed to a system and a method for hydride generation. In some embodiments, the system includes an assembly for introducing hydride generation reagents into a mixing path or mixing container, where the assembly includes first chamber configured to contain a first hydride generation reagent and a second chamber configured to contain a second hydride generation reagent. A first plunger is configured to translate within the first chamber and cause a displacement of the first hydride generation reagent, and a second plunger is configured to translate within the second chamber and cause a displacement of the second hydride generation reagent. The assembly further includes base coupling the first plunger and the second plunger together.

First claim

What is claimed is:

1. A system, comprising:
a first chamber configured to contain a first hydride generation reagent;
a second chamber configured to contain a second hydride generation reagent;
a first plunger configured to translate within the first chamber and cause a displacement of the first hydride generation reagent;
a second plunger configured to translate within the second chamber and cause a displacement of the second hydride generation reagent; and
a base coupling the first plunger and the second plunger together, the base vertically movable relative to the first chamber and the second chamber.

2. The system as recited in claim 1 , wherein the first plunger and the second plunger are moveably coupled to the base.

3. The system of claim 2 , wherein the first plunger and the second plunger are moveably coupled to the base by at least one pin extending through at least a portion of the base.

4. The system of claim 1 , wherein the first chamber and the second chamber are rigidly connected with one another.

5. The system of claim 4 , wherein the first chamber and the second chamber are portions of a common structure.

6. The system of claim 4 , further comprising one or more mounting members rigidly connected to the first and second chambers, the one or more mounting members configured for affixing the first and second chambers to a rigid structure.

7. The system of claim 6 , further comprising:
an actuator coupled to the rigid structure or the base; and
a controller configured to cause the actuator to actuate the rigid structure or the base to dispense a selected amount of the first hydride generation reagent and a selected amount of the second hydride generation reagent.

8. The system of claim 1 , further comprising:
a third chamber configured to contain a carrier solution; and
a third plunger configured to translate within the third chamber and cause a displacement of the carrier solution, wherein the base further couples the third plunger with the first plunger and the second plunger together.

9. The system of claim 8 , wherein a cross-sectional area of the first chamber is different from a cross-sectional area of the second chamber, or a cross-sectional area of the first chamber is different from a cross-sectional area of the third chamber, or a cross-sectional area of the second chamber is different from a cross-sectional area of the third chamber.

10. The system of claim 8 , wherein the third plunger is coupled with the base, and the base and the third plunger together are movable relative to the third chamber.

11. The system of claim 1 , wherein the first chamber and the second chamber are sized appropriately to dispense the first hydride generation reagent and the second hydride generation reagent in a ratio suitable for forming a hydride when mixed with a sample.

12. The system of claim 1 , wherein the first plunger and the second plunger are configured respectively to displace fluid within the first chamber and the second chamber in a synchronized manner when the base, the first plunger, and the second plunger together are moved relative to the first chamber and the second chamber.
