Methods for processing a vessel, for example to provide a gas barrier or lubricity, are disclosed. First and second PECVD or other vessel processing stations or devices and a vessel holder comprising a vessel port are provided. An opening of the vessel can be seated on the vessel port. The interior surface of the seated vessel can be processed via the vessel port by the first and second processing stations or devices. Vessel barrier, lubricity and hydrophobic coatings and coated vessels, for example syringes and medical sample collection tubes are disclosed. A vessel processing system and vessel inspection apparatus and methods are also disclosed.
1. A method for inspecting the product of a coating process wherein a coating has been applied by plasma enhanced chemical vapor deposition (PECVD) to at least a portion of the surface of a vessel to form a coated surface, the method comprising: (a) providing a product of the coating process having
1. A method for inspecting the product of a coating process wherein a coating has been applied by plasma enhanced chemical vapor deposition (PECVD) to at least a portion of the surface of a vessel to form a coated surface, the method comprising: (a) providing a product of the coating process having a plasma enhanced chemical vapor deposition coating on the surface;(b) providing a space that is a lumen of the vessel adjacent to the plasma enhanced chemical vapor deposition coating;(c) in a molecular flow mode of operation, measuring a release characteristic of at least one volatile species into the space adjacent to the plasma enhanced chemical vapor deposition coating;(d) identifying the release characteristic of the at least one volatile species from an acceptably coated surface of the inspection object; and(e) determining whether the release characteristic measured in step (c) satisfies the release characteristic identified in step (d). 2. The method of claim 1, wherein the vessel is an evacuated blood collection tube, a syringe barrel, or a vial. 3. The method of claim 1, further comprising connecting the lumen via a duct to a vacuum source and drawing at least a partial vacuum on the lumen before measuring the release characteristic. 4. The method of claim 3, further comprising providing an outgassing measurement cell communicating between the lumen and the vacuum source. 5. The method of claim 3, in which the lumen is evacuated to a pressure from 0.1 Torr to 100 Torr. 6. The method of claim 1, further comprising, before measuring the release characteristic, contacting the coating with a gas. 7. The method of claim 1, in which the gas comprises water vapor. 8. The method of claim 1, in which the gas comprises oxygen. 9. The method of claim 1, in which the gas comprises carbon dioxide. 10. The method of claim 1, in which the coating is a barrier layer having a thickness of less than 500 nm. 11. The method of claim 10, in which the barrier layer comprises SiOx, in which x, the atomic ratio of oxygen to silicon atoms, is from about 1.5 to about 2.9 as measured by X-ray photoelectron spectroscopy (XPS). 12. The method of claim 10, in which the release characteristic is measured under conditions effective to distinguish the presence or absence of the barrier layer. 13. The method of claim 12, in which the measurement of the presence or absence of the barrier layer is confirmed to at least a six-sigma level of certainty. 14. The method of claim 1, in which the plasma enhanced chemical vapor deposition coating is prepared from an organosilicon precursor. 15. The method of claim 1, in which the release characteristic is measured using micro-flow technology. 16. The method of claim 1, in which the release characteristic is measured by measuring the mass flow rate into the space adjacent to the coated surface. 17. The method of claim 16, in which the release characteristic is measured using micro-flow technology. 18. A method for inspecting the product of a coating process wherein a coating has been applied by plasma enhanced chemical vapor deposition (PECVD) to at least a portion of the surface of a vessel to form a coated surface, the method comprising: (a) providing a product of the coating process having a plasma enhanced chemical vapor deposition coating on the surface;(b) providing a space that is a lumen of the vessel adjacent to the plasma enhanced chemical vapor deposition coating;(c) measuring a release characteristic of at least one volatile species into the space adjacent to the plasma enhanced chemical vapor deposition coating using micro-flow technology;(d) identifying the release characteristic of the at least one volatile species from an acceptably coated surface of the inspection object; and(e) determining whether the release characteristic measured in step (c) satisfies the release characteristic identified in step (d). 19. The method of claim 18, further comprising connecting the lumen via a duct to a vacuum source and drawing at least a partial vacuum on the lumen before measuring the release characteristic. 20. The method of claim 19, further comprising providing an outgassing measurement cell communicating between the lumen and the vacuum source. 21. The method of claim 19, in which the lumen is evacuated to a pressure from 0.1 Torr to 100 Torr. 22. The method of claim 18, further comprising, before measuring the release characteristic, contacting the coating with a gas. 23. The method of claim 18, in which the release characteristic is measured under conditions effective to distinguish the presence or absence of the coating to at least a six-sigma level of certainty. 24. A method for inspecting the product of a coating process wherein a coating has been applied by plasma enhanced chemical vapor deposition (PECVD) to at least a portion of the surface of a vessel to form a coated surface, the method comprising: (a) providing a product of the coating process having a plasma enhanced chemical vapor deposition coating on the surface;(b) providing a space that is a lumen of the vessel adjacent to the plasma enhanced chemical vapor deposition coating;(c) measuring a release characteristic of at least one volatile species into the space adjacent to the plasma enhanced chemical vapor deposition coating by measuring the mass flow rate into the space adjacent to the coated surface;(d) identifying the release characteristic of the at least one volatile species from an acceptably coated surface of the inspection object; and(e) determining whether the release characteristic measured in step (c) satisfies the release characteristic identified in step (d). 25.
