<p>The object of the invention is a process for monitoring the dilution and contamination of a solution of given diluteness in which: before any dilution n, where n is a whole number greater than 0, a marker substance soluble in the solution and not interfering therewith is introduced into the solution of dilution n-1, while the marker substance has the property of disappearing between dilution n-1+m and n+m, where m is the number of dilutions in which the marker substance is present and is comprised particularly between 5 and 8; the marker substance is titred in at least once after dilution n; the concentration of the marker substance obtained is compared with that calculated after dilution. This process facilitates the qualitative and quantitative monitoring of the dilutions.</p> |
