Abstract: An ion chromatography housing for easy insertion and removal of a plurality of component cartridges is disclosed. Various components of the IC system are provided in the separate component cartridges. The IC housing includes a capillary separation column and may be connected to conventional-scale components of an IC system. A plurality of IC housings may be provided in a compartment with one or more separation columns. The columns may be capillary columns or conventional-scale columns. A method of using the ion chromatography system is also disclosed. The IC system may be utilized to perform two-dimensional ion chromatographic separation.

Abstract: A high-pressure capillary degas assembly includes an assembly block having an eluent inlet and an eluent outlet, and a separator support extending therebetween, a wash inlet and a wash outlet and a groove extending therebetween, a tubular separator extending within the assembly block, the separator having an inner surface and an outer surface, the inner surface defining an eluent fluid line fluidly interconnecting the eluent inlet and outlet, the outer surface abutting against the separator support and enclosing the groove to define a wash line within the groove. The separator may be configured to retain liquid in the eluent fluid line at a first pressure and allow gas to flow through the separator to the wash fluid line at a second pressure lower than the first pressure. A method of using the high-pressure capillary degas assembly is also disclosed.

Abstract: An apparatus for automated extraction of an analyte from a sample positioned in a sample containment cell having a fluid passageway structure for communication of an extraction fluid to and from the cavity of the cell. The apparatus includes a loading tray, an oven assembly mounted proximate the loading tray, a fluid communication assembly mounted proximate the tray, a cell manipulation assembly and a controller. The cell manipulation assembly brings an inlet conduit and an outlet conduit of the fluid communication assembly into sealed relationship with the sample containment cell and uses the conduits to pick up and move the cell to and from the cell tray and oven assembly.

Abstract: An extraction cell apparatus (10) for use in elevated pressure and temperature fluid extractions having a pressure resistant vessel (12) forming a cavity (11), and at least one shoulder portion (13) defining an opening (14) communicating with the cavity (11). An insert member (16) is provided engaging the vessel (12) proximate the shoulder portion (13), and a shoulder seal member (17) is positioned proximate the insert member (16). The seal member (17) is positioned for contact with the shoulder portion (13) upon mounting engagement of the insert member (16) with the seal member (17). An end cap (18) is formed for sliding receipt of the insert member (16) therein until an interior surface (19) of the end cap (18) contacts a backside of the seal member (17). An exterior force applied to the end cap (18) in an inwardly direction toward the shoulder portion (13) causing increasing sealing contact between the seal member (17) and the shoulder portion (13).
