<p>A diluting apparatus for use with a high performance liquid chromatography (HPLC) apparatus includes a multiport valve under automated control and an exponential mixing chamber connected to the multiport valve. The multiport valve receives the mobile phase from the detector of the apparatus and injects the liquid sample into the mobile phase. Then the sample and mobile phase are mixed in the exponential mixing chamber, and sent into the test column. The invention permits automatic dilution to a high precision, and also conserves the mobile phase solvnet used in the apparatus.</p> |
