The days of the necessity for intensive training on the theories underpinning the technology simply to provide competent use have long since passed. Now the requirement is for the analyst to be competent and proficient in the use of the technology, to produce reliable and defensible results on a routine basis with little or no formal guidance. I have found that this is case in my laboratory, and I believe the basic scenario is the same in laboratories throughout the world. I have attempted to address these needs in two other texts— through method review and summary in The HPLC Solvent Guide, 2nd edition, and through description of the use and maintenance of LCs in Troubleshooting HPLC Systems: A Bench Manual. This text aims at a slightly different need that lies beyond the basic use of chromatographic instrumentation. The commonplace use of chromatographic techniques in analyzing regulated products places an additional burden on the analyst: the proficient use of the basic data-handling terms is also expected. Therefore, the definitions of some fundamental statistical terms and concepts are included. It should be noted that there are
