Abstract

The invention provides ways to determine the impact of diluting a solution wherein the diluting may be carried out for any of a variety of purposes. In one embodiment, the method enables accurate volume dispensation calculations independent of meniscus shape. In another embodiment, the method enables accurate determination of plate washing efficiency. In yet another embodiment, the method enables the accurate determination of dilution ratio over a plurality of dilution steps. The methods described may be carried out using one or more systems arranged to perform the steps. A kit of the invention includes instructions for carrying out the steps of the methods and, optionally, one or more solutions suitable for conducting photometric measurements.
