Abstract

A new analytical chemistry experiment is described. It uses commercially available glucometers for purposes of error analysis. The glucometers measure reflectance from enzyme test strips to quantitate glucose concentrations in blood. Since the typical measurement takes less than two minutes, large data sets can be obtained by students in a reasonable amount of time for statistical analysis. Students are asked to design experiments to answer specific questions concerning the performance of the glucometers.
