Claims
- 1. A device for collecting residue, comprising:
a first barrel section, a sponge removably mounted to said first barrel section, a first end cap removably mounted to said first barrel section, a second barrel section, a pipette tip removably mounted to said second barrel section, and a second end cap removably mounted to said second barrel section.
- 2. The device of claim 1, additionally including a vial mounted in said second end cap.
- 3. The device of claim 1, wherein said first barrel section includes a reduced diameter section at opposite ends thereof, said first end cap and said second barrel section being removably mounted to said reduced diameter and sections.
- 4. The device of claim 3, additionally including seal means mounted on each said reduced diameter section of said first barrel section.
- 5. The device of claim 4, wherein each said seal means includes a groove in said reduced diameter section and an σ-ring located in said groove.
- 6. The device of claim 1, additionally including seal means located intermediate said first end cap and said first barrel section, intermediate said first barrel section and said second barrel section, and intermediate said second barrel section and said section end cap.
- 7. The device of claim 1, wherein said sponge is mounted to said first barrel section via a member removably mounted in a cavity in said first barrel section.
- 8. The device of claim 1, wherein said second barrel section includes an opening extending therethrough and two reduced diameter sections of which one section is smaller in diameter than the other section, said second end cap being removably mounted to said one section, and said pipette tip being removably mounted to said other section.
- 9. The device of claim 8, wherein said one section of said two reduced diameter sections is provided with a seal means.
- 10. The device of claim 8, wherein said seal means comprise a groove in said one section and an σ-ring mounted in said groove.
- 11. The device of claim 1, wherein said first end cap is hermetically sealed to said first barrel section, said second barrel section is hermetically sealed to said first barrel section, and said second end cap is hermetically sealed to said second barrel section.
- 12. The device of claim 11, additionally including a vial mounted in said second end cap.
- 13. The device of claim 12, additionally including a quantity of solvent in said first end cap.
- 14. A residue applicator sampler, particularly adapted for use in thin layer chromatography, comprising:
means including a wetted sponge for sampling an analyte of interest, means for transporting said wetted sponge, means for receiving the sample from the wetted sponge, and means for containing the received sample from said means for receiving the sample.
- 15. The sampler of claim 14, wherein said means for transporting said wetted sponge includes a housing, a removable end cap extending around said wetted sponge and mounted to said housing, and seal means intermediate said end cap and said housing.
- 16. The sampler of claim 14, wherein said means for receiving the sample includes a hollow member removably mounted to said housing, seal means located intermediate said housing and said removable hollow member, and a pipette tip mounted to said removable hollow member.
- 17. The sampler of claim 14, wherein said means for containing said received sample includes a vial mounted in a removable end cap adapted to the mounted to said hollow member, and seal means located intermediate said removable end cap and said hollow member.
- 18. The sampler of claim 14, wherein said welted sponge is hermetically sealed in said means for transporting, said means for receiving the sample is hermetically sealed to said means for transporting, and said means for containing the received sample is hermetically sealed to said means for receiving the sample.
- 19. The sampler of claim 14, wherein said transporting means, said receiving means, and said containing means is constructed to form a longitudinally extending annular device having a body section and two removable end cap hermetically seal to said body section, and wherein said body section comprises a pair of removable barrel sections hermetically sealed together, and of said barrel sections being hollow.
- 20. The sampler of claim 19, wherein said longitudinally extending device has a length of less than six inches and a diameter of about ⅜ inch.
