ABSTRACT:
A sampling apparatus is disclosed including a sample container with a removable cap; an inlet conduit adapted for introducing a stream of fluid into the sample container; an outlet conduit adapted for removing a stream of fluid from the sample container; a valve in the inlet conduit for passing a stream therethrough and into the sample container; a valve in the outlet conduit for passing a stream therethrough and out of the sample container; and a controller for actuating the valve in said inlet and outlet conduits at a predetermined time interval such that a stream of fluid is passed into the sample container until the container is filled with the fluid. A method of collecting samples with a zero headspace in the collection sample container is also disclosed utilizing the above sampling apparatus.
