It is appropriate for a report of this kind to compare its findings with those of others who have done similar evaluations. For four of the analyzers considered—two of which were characterized as having acceptable accuracy and precision and two of which were reported to have unacceptable accuracy and precision—supporting data from other publications were presented. In only one case, that of the DuPont Analyst, which was characterized as having acceptable precision but poor accuracy, did the authors fail to refer to any other published works, of which there are several.
