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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The system as recited in claim 1, wherein the first plunger and the second plunger are moveably coupled to the base. ### Claim 3 (depends on 2) 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. ### Claim 4 (depends on 1) The system of claim 1, wherein the first chamber and the second chamber are rigidly connected with one another. ### Claim 5 (depends on 4) The system of claim 4, wherein the first chamber and the second chamber are portions of a common structure. ### Claim 6 (depends on 4) 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. ### Claim 7 (depends on 6) 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. ### Claim 8 (depends on 1) 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. ### Claim 9 (depends on 8) 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. ### Claim 10 (depends on 8) 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. ### Claim 11 (depends on 1) 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. ### Claim 12 (depends on 1) 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.
