A method, apparatus, and system for controlling an environment within a container having at least one material type. An inert gas is introduced into the container to displace any harmful atmospheric components that may be present in the container, which could react with the solid material in the container. The displaced harmful atmospheric components are expelled from the container to a measuring device which identifies the concentration of the expelled components. The amount of inert gas being introduced into the container may be controlled in response to the measured results. |

| Claim: |
1. An apparatus for controlling an environment within a container capable of containing at least one material type, said method comprising: means for introducing an amount of an inert gas into said container containing said at least one material type; and means for measuring an amount of harmful atmospheric components expelled from said container as said inert gas is introduced. |
| Claim: |
2. The apparatus of claim 1 further comprising means for adjusting said amount of said inert gas being introduced into said container in response to said measured amount of said harmful atmospheric components. |
| Claim: |
3. The apparatus of claim 1 wherein said material type comprises a solid material capable of being used to manufacture a flux powder used in arc welding. |
| Claim: |
4. The apparatus of claim 1 wherein said material type comprises a flux powder capable of being used to manufacture flux-cored arc welding electrodes. |
| Claim: |
5. The apparatus of claim 1 wherein said harmful atmospheric components include molecules of moisture. |
| Claim: |
6. The apparatus of claim 1 wherein said harmful atmospheric components include molecules of at least one of water, oxygen, carbon dioxide, and hydrogen. |
| Claim: |
7. The apparatus of claim 1 wherein said container comprises a storage device capable of storing said material type. |
| Claim: |
8. The apparatus of claim 1 wherein said container comprises a delivery device capable of delivering said material type to another device. |
| Claim: |
9. The apparatus of claim 1 wherein said container is substantially closed to inhibit external harmful atmospheric components from entering said container. |
| Claim: |
10. The apparatus of claim 1 wherein said inert gas comprises at least one of argon, helium, neon, krypton, xenon, radon, and molecular nitrogen. |
| Claim: |
11. A system for controlling an environment within a container capable of containing at least one material type, said system comprising: a container capable of containing at least one material type; an inert gas supply operationally connected to said container and capable of introducing an inert gas into said container capable of containing said at least one material type; and a measuring device operationally connected to said container and capable of measuring an amount of harmful atmospheric components expelled from said container as said inert gas is introduced. |
| Claim: |
12. The system of claim 11 further comprising a feedback controller operationally connected between said measuring device and said inert gas supply and capable of adjusting said amount of said inert gas being introduced into said container by said inert gas supply in response to said measured amount of said harmful atmospheric components. |
| Claim: |
13. The system of claim 11 wherein said material type comprises a solid material capable of being used to manufacture a flux powder used in arc welding. |
| Claim: |
14. The system of claim 11 wherein said material type comprises a flux powder capable of being used to manufacture flux-cored arc welding electrodes. |
| Claim: |
15. The system of claim 11 wherein said container comprises a storage device capable of storing said material type. |
| Claim: |
16. The system of claim 11 wherein said container comprises a delivery device capable of delivering said material type to another device. |
| Claim: |
17. The system of claim 11 wherein said measuring device comprises a Fourier transform infrared spectrometer. |
| Claim: |
18. The system of claim 12 wherein said feedback controller comprises a processor-based platform. |
| Claim: |
19. A method of controlling an environment within a container capable of containing at least one material type, said method comprising: introducing an inert gas at a first flow rate into said container containing said at least one material type such that said inert gas expels harmful atmospheric components from said container; and continuously or periodically measuring an amount of said harmful atmospheric components expelled from said container. |
| Claim: |
20. The method of claim 19 further comprising continuously or periodically adjusting said flow rate of said inert gas being introduced into said container in response to said measured amount of said harmful atmospheric components. |
| Claim: |
21. The method of claim 19 wherein said material type comprises a solid material capable of being used to manufacture a flux powder used in arc welding. |
| Claim: |
22. The method of claim 19 wherein said material type comprises a flux powder capable of being used to manufacture flux-cored arc welding electrodes. |
| Claim: |
23. The method of claim 19 wherein said harmful atmospheric components include molecules of moisture. |
| Claim: |
24. The method of claim 19 wherein said harmful atmospheric components include molecules of at least one of water, oxygen, carbon dioxide, and hydrogen. |
| Claim: |
25. The method of claim 19 wherein said container is substantially closed to inhibit external harmful atmospheric components from entering said container. |
| Claim: |
26. The method of claim 19 wherein said inert gas comprises at least one of argon, helium, neon, krypton, xenon, radon, and molecular nitrogen. |
