Integrated chromatography column injector detector device

A chromatography device comprising:

• a body bounded by an external surface and having upstream inlet and downstream outlet ports, first and second connection ports, and at least one detector port, said ports extending inwardly from said external surface;
• a sample injector for carrying sample to be analyzed removably mounted in the first connection port and having an upstream inlet and a downstream outlet, said injector inlet communicating with the body inlet port through a connecting passageway;
• a chromatography column having one end removably mounted in the second connection port and having at said column one end an upstream inlet and a downstream outlet located in the second connection port when the column is mounted;
• a detector for chromatography measurement located at the detector port;
• and,
• said body defining a first internal flow passageway between the first connection port and the second connection port providing fluid communication between the downstream outlet of a sample injector mounted in the first connection port and the upstream inlet of a chromatography column mounted in the second connection port;
• said body defining a second internal flow passageway between the second connection port and the outlet port providing fluid communication between the downstream outlet of a chromatography column mounted in the second connection port and a segment of the second internal flow passageway extending past the detector;
• and,
• whereby fluid enters the input port of said body and exits the output port of said body.

A chromatography device comprising:

• a solid body bounded by an external surface and having upstream inlet and downstream outlet ports, first and second connection ports, and at least one detector port, said ports extending inwardly from said external surface;
• a connector coupling removably mounted in the inlet port defining an internal connecting passageway extending axially between inner and outer ends, the outer end being adapted to receive an external connection, the connector coupling having an external thread for cooperatively engaging an internal thread formed in the input port to secure the connector coupling thereto;
• a sample injector removably mounted in the first connection port, and the sample injector having a tubular stem for carrying sample to be analyzed with an upstream inlet at one end and a downstream outlet spaced from said one end, said stem extending into the inner end of the connecting passageway when said injector is mounted, the sample injector having an external thread for cooperatively engaging an internal thread formed in the first connection port to secure the sample injector thereto;
• a chromatography column having one end removably mounted in the second connection port and having at said column one end an upstream inlet and a downstream outlet located in the second connection port when said column is mounted, the chromatography column having an external thread for cooperatively engaging an internal thread formed in the second connection port to secure the chromatography column thereto;
• a detector for chromatography measurement located at the detector port;
• said body defining a first internal flow passageway between the first connection port and the second connection port providing fluid communication between the downstream outlet of a sample injector mounted in the first connection port and the upstream inlet of a chromatography column mounted in the second connection port;
• said body defining a second internal flow passageway between the second connection port and the outlet port providing fluid communication between the downstream outlet of a chromatography column mounted in the second connection port and a segment of the second internal flow passageway extending past the detector;
• and,
• whereby fluid enters the input port of said body and exits the output port of said body.
