Abstract
The present invention relates to an injection valve for an analysis apparatus comprising an analysis column, the injection valve comprising a rotative body compressed against a base by a compressive element, the rotative body comprising a lower surface in contact with the base and at least one recess on the lower surface configured to receive a fluid sample, wherein the base comprises a vaporization chamber which comprises an injection conduit having an upper end and a lower end, the vaporization chamber further comprising a carrier phase inlet in fluid communication with the injection conduit, wherein the injection conduit is configured for being in fluid communication with the analysis column of the analysis apparatus via the lower end when the injection valve is mounted on the analysis apparatus, and wherein, in an injection configuration of the rotative body, the recess is in fluid communication only with the injection conduit, via the upper end thereof. The present invention further relates to an analysis set comprising said injection valve and to a method of analyzing a fluid in said analysis set.
