Disclosed embodiments of the apparatus address the challenges of rotary PSA systems, both axial and radial flow, with M>1 by providing interpenetrating, layered manifolds to accommodate all of the steps of a complex PSA cycle, suitable with equal compactness for any value of "M". This approach extends readily to accommodate a plurality of rotary PSA modules and their cooperating compression machinery within a single layered manifold assembly for a single PSA plant train. Described embodiments of the rotary PSA apparatus include stators that define fluid ports. In particular embodiments of the described apparatus, a second stator defines pressure swing adsorption cycle sectors, each sector being defined by a light product delivery port, light product withdrawal ports, and light reflux return ports. The adsorber elements may directly contact one or more of the stators in a fluidly sealing manner (i.e., have a clearance gap of from about 0 to about 50 microns) using described reinforced adsorbers. The method comprises providing an embodiment of the described apparatus and then supplying at least one feed fluid to pressurize an adsorber element of the adsorber sets to substantially a higher pressure to initiate a pressure swing adsorption cycle.

An injection liner for use in the injector of a gas chromatograph, the liner being in the form of an elongate tube having an input end and an output end, the input end bearing a laterally-extending external flange. 2. An injection liner as claimed in claim 1, wherein the liner's output end is associated with a restriction. 3. An injection liner as claimed in claim 2, wherein the flange has a number of concentrically-circular ridges on its septum-facing surface. 4. An injection liner as claimed in claim 3, wherein the liner includes a special gas input aperture positioned between its ends and between this aperture and the liner's output end there is exterior sealing means. 5. An injection liner as claimed in claim 4, wherein the sealing means is an O-ring, suitably mounted around the exterior of the liner between ridges on the outside of the liner. 6. An injection liner as claimed in claim 1, wherein the flange has a number of concentrically-circular ridges on a surfacing facing away from said tube. 7. An injection liner as claimed in claim 1, wherein the liner includes a special gas input aperture positioned between its ends and between this aperture and the liner's output end there is exterior sealing means. 8. An injection liner as claimed in claim 7, wherein the sealing means is an O-ring suitably mounted around the exterior of the liner between ridges on the outside of the liner. 9. An injection liner, as claimed in claim 1, in combination with an injection septum, arranged to fit over the liner's input end and to fit sealingly against the liner's flange, and a closure cap arranged to fit tightly over and around the septum and the flange so as to hold the septum sealingly against the flange and close the input end. 10. An injection liner as claimed in claim 9, wherein the input end has a thread thereon and the closure cap screws thereonto. 11. An injection liner combination as claimed in claim 10, wherein the septum is a disc-shaped object matching the dimensions of the liner's flanged input end and made of a silicone rubber protected by a coating on each side in the form of a layer of polytetrafluoroethylene (PTFE). 12. An injection liner combination as claimed in claim 10, wherein the closure cap is made from, or encloses, magnetic material. 13. An injection liner combination as claimed in claim 12, wherein the closure cap extends in use laterally beyond the boundaries of the tube and flange and provides a sealing surface. 14. An injection liner combination as claimed in claim 10, wherein the closure cap extends in use laterally beyond the boundaries of the tube and flange and provides a sealing surface. 15. An injection liner combination as claimed in claim 9, wherein the septum is a disc-shaped object matching the dimensions of the liner's flanged input end and made of a silicone rubber protected by a coating on each side in the form of a layer of polytetrafluoroethylene (PTFE). 16. An injection liner combination as claimed in claim 15, wherein the closure cap is made from, or encloses, magnetic material. 17. An injection liner combination as claimed in claim 16, wherein the closure cap extends in use laterally beyond the boundaries of the tube and flange and provides a sealing surface. 18. An injection liner combination as claimed in claim 15, wherein the closure cap extends in use laterally beyond the boundaries of the tube and flange and provides a sealing surface. 19. An injection liner combination as claimed in claim 9, wherein the closure cap is made from, or encloses, magnetic material. 20. An injection liner combination as claimed in claim 19, wherein the closure cap extends in use laterally beyond the boundaries of the tube and flange and provides a sealing surface. 21. An injection liner combination as claimed in claim 9, wherein the closure cap extends in use laterally beyond the boundaries of the tube and flange and provides a sealing surface.
