![]() ![]() When performing a dilution there is a equation that can be used to determine the final concentration. By performing a dilution on a sample it may reduce the interfering substance to a point where it no longer interferes with the test. If the Mn+6 is present in the sample it will add to the value of the chlorine test due to the way the it reacts to the chlorine test reagents. For example, oxidized manganese (Mn+6) acts as an interference to the chlorine test. The easiest method is to make a series of 1 in 10 dilutions. An example is if performing a chlorine test, chlorine would be the analyte.Īn interference is a compound that can add to, or subtract from the result of the analysis. A serial dilution is a series of sequential dilutions used to reduce a dense culture of cells to a more usable concentration. Dilutions can be important when dealing with an unknown substance.Ī dilution can be performed not only to lower the concentration of the analyte that is being tested, so that it is in range, but also to help eliminate interferences from other substances that may be present in the sample that can artificially alter the analysis.Īn analyte is the compound in the sample that is desired to be tested. ![]()
