High Dilution Ratio by Successively Preparing and Diluting Chemicals

摘要

A system and method for providing a plurality of diluted solutions are disclosed. Successive dilution operations are performed upon mixing vessels substantially simultaneously. Measured source volumes of a source solution are placed into the mixing vessels. First measured volumes of a liquid are added to the mixing vessels. Measured first waste volumes are dispensed from the mixing vessels. Second measured volumes of the liquid are added to the mixing vessels. Measured second waste volumes are dispensed from the mixing vessels. Third measured volumes of the liquid are added to the mixing vessels. Each vessel has an individual target dilution ratio. Measured volumes and number of dilution operations are individual to each of the mixing vessels.

1. A method for providing a plurality of diluted solutions, comprising:
placing a first volume of a first solution into each mixing vessel of a plurality of mixing vessels; adding a second volume of a liquid to each mixing vessel of the plurality of mixing vessels, to form second solutions having first dilution ratios; for a first portion of the plurality of mixing vessels, dispensing a first waste volume of the second solutions; for the first portion of the plurality of mixing vessels, adding a third volume of the liquid to form third solutions having second dilution ratios; for a subset of the first portion of the plurality of mixing vessels, dispensing a second waste volume of the third solutions; and for the subset of the first portion of the plurality of mixing vessels, adding a fourth volume of the liquid to form fourth solutions having third dilution ratios; wherein the adding the second volume is performed substantially simultaneously for each mixing vessel of the plurality of mixing vessels, and wherein the dispensing the first waste volume and the adding the third volume are each performed substantially simultaneously for each mixing vessel of the first portion of the plurality of mixing vessels.
