The sample carrier of claim 4, wherein the identifier is a color code to indicate at least one of the depth of use of the carrier and the order of use of the carrier. 9. The sample carrier of claim 1, wherein the volume is about 70 microliters. 10. The sample carrier of claim 1, wherein the shell has a generally spheroid shape. 11. The sample carrier of claim 1, wherein the shell includes means for identifying the carrier and means for non-intrusively traveling in drilling mud. 12. A sample carrier to retrieve a sample out of a borehole, comprising: a shell having an interior hollow; a mandrel having a recessed portion between two sealing assemblies adapted to seal the interior hollow to retain a volume of a formation fluid, and wherein the mandrel is transparent to a signal used in testing the sample in the volume. 13. The sample carrier of claim 12, wherein the shell includes a sleeve and a jacket surrounding the sleeve, and wherein the jacket and sleeve are buoyant in drilling mud. 14. The sample carrier of claim 13, wherein the sleeve and the mandrel form a sealable volume there between to hold a formation fluid sample. 15. The sample carrier of claim 14, wherein the mandrel includes seals for contact with the sleeve to seal the volume. 16. The sample carrier of claim 15, wherein the jacket includes an identifier. 17. The sample carrier of claim 16, wherein the identifier is a fluorescent material. 18. The sample carrier of claim 16, wherein the identifier is a radio frequency identification. 19. The sample carrier of claim 16, wherein the identifier is a bar code. 20. The sample carrier of claim 16, wherein the identifier is a color code to indicate at least one of the depth of use of the carrier and the order of use of the carrier. 21. A sample carrier to retrieve a sample out of a borehole, comprising: a shell having an interior hollow; a mandrel adapted to seal the interior hollow with a volume of a formation fluid, and wherein the mandrel includes a coating to adhere to a specific chemical that may be found in the formation. 22. A formation sampling system, comprising: a sample loading assembly adapted to be operative downhole and to repeatedly engage a formation wall of a borehole; and a plurality of sample carriers to be loaded by the sample loading assembly and to be released into drilling mud, each sample carrier comprising: a sleeve defining a cavity; a mandrel sized to fit within the cavity and including a sampling recess between two sealing assemblies, the mandrel adapted to move within the cavity to receive fluid within a sample chamber defined by the sampling recess and the cavity, the fluid received from the sample loading assembly, and the mandrel further adapted to seal the sample chamber to retain the received fluid. 23. The system of claim 22, each sample carrier further comprising a jacket portion that is buoyant relative to drilling mud within the bore hole, wherein the sleeve and the jacket portion form a shell. 24. A formation sampling system, comprising: a sample loading assembly adapted to be operative downhole; a sample carrier to be loaded by the sample loading assembly and released into drilling mud; wherein the sample carrier includes a shell having an interior hollow and a mandrel including a sample receiving recess between two sealing assemblies, the mandrel adapted to move within the interior hollow to receive a formation fluid sample and to seal the interior hollow with to retain a volume of the formation fluid sample in the interior hollow; wherein the sample loading assembly is adapted to load the formation fluid sample; and wherein the sample loading assembly includes a carrier loader adapted to remove the mandrel from the shell, expose the sample receiving recess to the fluid sample, and reinsert the mandrel into the shell. 25. The system of claim 24, wherein the shell is buoyant in drilling mud and includes a sleeve and a jacket surrounding the sleeve, wherein the two sealing assemblies are adapted to contact the sleeve to retain the formation fluid sample. 26. The system of claim 25, wherein sample loading assembly includes a formation fluid extracting device operatively coupled to the carrier loader, the extracting device being adapted to engage the formation wall and extract a sample. 27. The system of claim 26, wherein the formation fluid extracting device includes a sample line to deliver the sample to the carrier loader and includes a pressure system to extract fluids from the formation. 28. The system of claim 27, wherein the formation fluid extracting device includes a seal to engage the formation wall, a snorkel within the seal to remove a sample from the formation, and a sampling system controller to control the seal and the snorkel. 29. The system of claim 28, wherein the sample line is in fluid communication with the carrier loader. 30. The system of claim 29, wherein the carrier loader includes a downhole power source. 31. The system of claim 30, wherein the formation fluid extracting device includes a downhole power source. 32. The system of claim 30, further comprising an extraction device for removing the sample carrier from the drilling mud. 33. The system of claim 32, wherein the extraction device is positioned at the surface and includes mechanical devices to remove the sample carrier. 34. The system of claim 32, wherein the extraction device includes a cleaner to remove the drilling mud from the sample carrier. 35.
