VESSEL INSPECTION APPARATUS AND METHODS
First Claim
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) 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).

Abstract
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
