SAMPLE DILUTION WITH A PLURALITY OF PARALLEL FLOW RESTRICTION MEANS

摘要

Two conduit means having a preselected volumetric relationship one to the other, at least one of these conduit means having a plurality of parallel passageways having different flow transmission time characteristics, are utilized in the dilution of a sample by filling one of the conduit mean with a diluent liquid and the other with a sample material, then connecting the two conduit means together in a closed conduit loop and circulating the contents of the loop through the loop in order to cause uniform mixing of the sample material with the diluent liquid. In a preferred embodiment the diluted sample material is resampled from the conduit loop for further use or analysis.
