Solid-state flow generator and related systems, applications, and methods
The invention, in various embodiments, is directed to an analyzer using a solid-state flow generator to provide effluent flow along a flow path and deliver a sample to an ion mobility based filter and detector for analysis.
1. A sample analyzer comprising:
an inlet for receiving an effluent including a sample,
a solid state flow generator including:
a first ion source, and
an ion attractor in fluid communication with the ion source for attracting ions from the ion source to generate a flow of the effluent through a flow path, and
an ion mobility based analyzer along the flow path including:
an ion mobility based filter for passing selected sample ions through a time-varying field, and
a detector for detecting the ions exiting the ion mobility based filter.
2. The analyzer of claim 1 , wherein the solid state flow generator feeds the effluent to the ion mobility based filter.
3. The analyzer of claim 1 , wherein the solid state flow generator draws the effluent to the ion mobility based filter.
4. The analyzer of claim 1 , wherein the flow path has first and second ends, the first ion source being located outside of the flow path proximal to the first end, the flow path being between the first ion source and the second end to cause the effluent flow to be in a direction from the first end toward the second end.
5. The analyzer of claim 1 , wherein the flow path has a plurality of axially extending sides.
6. The analyzer of claim 5 , wherein at least one of the axially extending sides is open along at least a portion of it's length.
7. The analyzer of claim 1 , wherein the flow path has an ovular cross-sectional shape.
8. The analyzer of claim 1 , wherein the flow path has an opening extending along at least a portion of it's length.
9. The analyzer of claim 1 , wherein at least one side of a portion of the flow path is defined by a component on an integrated circuit board.
10. The analyzer of claim 1 , wherein at least one side of a portion of the flow path is defined by a substrate.
11. The analyzer of claim 1 including a second inlet located along a length of the flow path for allowing a fluid to be introduced into the flow path for mixing with the effluent flow.
12. The analyzer of claim 11 , wherein the fluid includes a dopant.
13. The analyzer of claim 11 , wherein the time-varying field includes an asymmetric field.
14. The analyzer of claim 1 including a second ion source for generating sample ions.
15. The analyzer of claim 1 , wherein the ion mobility based filter includes at least one of a DMS and IMS.
16. The analyzer of claim 1 , wherein the detector includes at least one of a detector electrode, MS, and TOFMS.
17. The analyzer of claim 1 comprising a gas chromatograph in communication with the sample inlet or along the flow path.
18. The analyzer claim 1 , wherein the analyzer is of a hand-held size or smaller.
