Robustness and Ruggedness; Scale of Operation; Equipment, Time, and Cost; Making the Final Choice; A method is the application of a technique to a specific analyte in a specific matrix. The robustness/ruggedness of an analytical procedure is a measure of its capacity to remain unaffected by small, but deliberate variations in the method parameters and (1) the analytical procedure has to be validated as a whole, including sample treatments prior to analy-sis; (2) the analytical procedure has to be validated cover-ing the full range of analyte concentrations specified in the method scope; and, (3) the analytical procedure has to be validated for each kind of matrix where it will be applied. The robustness of an analytical procedure is defined as a measure of its capacity to obtain comparable and acceptable results when perturbed by small but deliberate variations in procedural parameters listed in the documentation.

The terms ruggedness and robustness as used in method validation are sometimes considered to be equivalent [1,2], In other publications a difference is made between the two terms [3]. Review of the use of Robustness and Ruggedness in Analytical Chemistry. The definitions and the different aims of such studies are given. Unfortunately, methods are subject to a variety of chemical and physical interferences that contribute uncertainty to the analysis. References.

The characteristics of robustness and ruggedness which express resistance against conditions and influences which decrease both precision and accuracy of analytical results, obtained by a particular procedure in a given laboratory or in different laboratories, can be treated quantitatively by the introduction of two new concepts, namely, relative robustity and relative ruggedness.
