The present invention relates generally to an apparatus and method for sample analysis. More particularly, the invention encompasses a method and an apparatus for continuous, constant, flow sample introduction of fluid samples of varying viscosity and composition. The invention further includes the option of the apparatus being associated with at least one fluid analyzer system. A temperature controlled environment may also be provided for the processing and analysis of a fluid sample.

Continuous flow sample introduction apparatus and method

A multiport, diaphragm sealed valve suitable for use as both a sampling and column switching valve. The valve is constructed to internally block fluid communication between one or more pairs of ports in a valve operating mode. Such blocking may be used to conserve carrier gas when the valve is in the ON position.

Gas chromatograph sample and column-switching valve

A chromatograph sample homogenizer having a mixing chamber containing means for homogenizing a mixture therein and means of controlled ingress and/or controlled egress for (1) eluant from a chromatographic column, (2) wash solvent, (3) transport gas, (4) waste material, and (5) homogenized sample. Methods for manipulating the operation of the sample homogenizer to provide homogenized samples and homogenized diluted samples.
