Abstract
An analysis system includes sample insertion module structure with structure defining a reduced pressure reservoir, structure defining a sample region, and structure defining a reagent circuit that includes metering chamber structure in series with the reagent circuit. First transfer valve structure is arranged to couple the sample region to the reagent circuit on one side of the metering chamber structure, and second transfer valve structure is arranged to couple the reagent circuit to the reduced pressure reservoir structure on the side of the metering chamber structure remote from the first transfer valve structure for inserting an intact metered quantity of sample liquid into a reagent stream.
