Abstract

A gas separation cartridge including a housing comprising an inlet port for an air sample to enter; a top cover attached to the housing; an upper cavity comprising individual chambers comprised of a chemical or an absorbent or a mixture thereof attached to the top cover wherein each end of each chamber has an opening; a bottom cover attached to the upper cavity, wherein the bottom cover comprises a lower cavity, a separate opening for an air sample traveling from an individual chamber to pass through, and a separate opening for an air sample that does not pass through an individual chamber; and a base upon which the bottom cover of the cartridge is seated, wherein the base has an exit port.

First claim

The invention claimed is:

1. A gas separation cartridge comprising a housing containing multiple individual passages, which are physically separated by a gas impermeable, inert barrier;
an inlet port configured to receive an air sample in the housing;
an exit port configured to pass air out of the housing;
wherein each passage comprises a chemical or an absorbent or a mixture thereof, wherein the chemical, the absorbent, or the mixture thereof is configured to remove one or more species from the air sample;
two tabs on the outside surface of the housing, each tab residing near a tip of a gas separation tube, which tabs are each connected to an individual lever inside the cartridge, which individual levers are located near the tips of the gas separation tube;
wherein the housing is configured to provide a selective flow path through the inlet port, through one of the multiple individual passages, and out through the exit port;
wherein each end of each passage is sealed.

2. The gas separation cartridge of claim 1 , wherein the shape of the cartridge is cylindrical.

3. The gas separation cartridge of claim 1 , wherein the housing comprises a solid material selected from the group consisting of glass, ceramic, acrylonitrile butadiene styrene, polyethylene, polypropylene, polyvinylchloride, derivatives thereof, and mixtures thereof.

4. The gas separation cartridge of claim 1 , further comprising a selection component configured to rotate and allow selection of a passage from the multiple individual passages.

5. The gas separation cartridge of claim 1 , wherein the chemical comprises carbon.

6. The gas separation cartridge of claim 1 , wherein the multiple individual passages comprise individual tubes or individual chambers.

7. The gas separation cartridge of claim 6 , wherein the individual tubes comprise glass.

8. The gas separation cartridge of claim 6 , wherein the individual tubes comprise a cylindrical shape.

9. The gas separation cartridge of claim 1 , further comprising a filter to remove particulate matter.

10. The gas separation cartridge of claim 1 , wherein the housing comprises:
a) an inlet port for an air sample to enter;
b) an upper lid attached to the inlet port;
c) a first sealing element attached to the upper lid;
d) a tube support stand attached to the first sealing element;
e) a second sealing element attached to the tube support stand; and
f) a lower lid attached to a second sealing element wherein the lower lid comprises an exit port.

11. The gas separation cartridge of claim 10 , further comprising at least one gas separation tube attached to the tube support stand and to the inlet port.

12. The gas separation cartridge of claim 11 , wherein the at least one gas separation tube comprises glass.

13. The gas separation cartridge of claim 10 , comprising a cavity attached to the inlet port through which a non-treated air sample can travel to a gas sensor.

14. The gas separation cartridge of claim 10 , further comprising an extension configured to sample air.

15. The gas separation cartridge of claim 10 , wherein the lower lid is attached to a switch containing multiple openings and passages for the air sample to separately flow through to the gas sensor.

16. The gas separation cartridge of claim 10 , wherein a switch is connected to a tube selection component, which is rotatable.

17. The gas separation cartridge of claim 1 , wherein
the housing comprises an inlet port for an air sample to enter; wherein the gas separation cartridge further comprises:
a top cover attached to the housing;
an upper cavity, wherein the multiple individual passages comprise individual chambers attached to the top cover, wherein each end of each individual chamber has an opening;
a bottom cover attached to the upper cavity, wherein the bottom cover comprises a lower cavity, a separate opening for an air sample traveling from an individual chamber to pass through, and a separate opening for an air sample that does not pass through an individual chamber to pass through; and
a base upon which the bottom cover of the cartridge is seated, wherein the base comprises an exit port.

18. The gas separation cartridge of claim 17 , wherein the housing comprises a solid material selected from the group consisting of glass, ceramic, acrylonitrile butadiene styrene, polyethylene, polypropylene, polyvinylchloride, derivatives thereof, and mixtures thereof.

19. The gas separation cartridge of claim 17 , wherein the multiple individual chambers comprise a chemical or an absorbent or a mixture thereof.

20. The gas separation cartridge of claim 19 , wherein the chemical comprises carbon.
