Claims
- 1. A method of inactivating one or more virions in a fluid containing a biological material potentially associated with a virion comprising:
- a) contacting a fluid containing a biological material with a critical, supercritical or near critical fluid by introducing said fluid containing a biological material into a vessel which contains said critical, supercritical or near critical fluid, under nonturbulent conditions which have a Reynolds Number less than or equal to 2,000 wherein said contacting is under conditions sufficient to inactivate the virion if present; and,
- b) removing said critical, supercritical or near critical fluid from said fluid containing said biological material and said virion, if present, to render said virion inactive.
- 2. The method of claim 1, wherein said contacting is performed with a nozzle injecting said material into a vessel containing said supercritical, critical or near critical fluid.
- 3. The method of claim 2, wherein said nozzle releases droplets or a stream of sample.
- 4. The method of claim 1 wherein said material comprises a biological substance selected from the group consisting of proteins, and biologically active small molecules.
- 5. The method of claim 1 wherein said critical, supercritical or near critical fluid has a temperature in the range of approximately 0.degree. C. to 100.degree. C.
- 6. The method of claim 1 wherein said critical, supercritical or near critical fluid has a temperature in the range of approximately 4.degree. C. to 60.degree. C.
- 7. The method of claim 1 wherein said critical, supercritical or near critical fluid is selected from one or more compounds of the group consisting of fluorocarbons, and alkanes.
- 8. The method of claim 7 wherein said fluorocarbons is selected from one or more compounds of the group consisting of chlorodifluoromethane and trifluoromethane.
- 9. The method of claim 7 wherein said alkanes is selected from one or more compounds of the group consisting of ethylene, propane and ethane.
- 10. The method of claim 1 wherein said critical, supercritical or near critical fluid is selected from one or more compounds of the group consisting of nitrous oxide, nitrogen and carbon dioxide.
- 11. The method of claim 1 wherein said critical, supercritical or near critical fluid has a temperature in the range of approximately 0.degree. C. to 100.degree. C.
- 12. A method of inactivating one or more virions in a biological fluid comprising:
- a) contacting said biological fluid and a supercritical fluid or a critical fluid by introducing said biological fluid into a vessel which contains said supercritical or critical fluid, through a nozzle which releases droplets or a stream of the sample under a nonturbulent condition which has a Reynolds Number less than or equal to 2,000, wherein said contacting is for a sufficient time to inactivate said virion; and
- b) removing said supercritical or critical fluid from the biological fluid.
