Laboratory Experiments
Practicing Quality Control in a Bioanalytical Experiment
Juliana Marcos, Angel Ríos, and Miguel Valcárcel
Department of Analytical Chemistry, University of Cordoba, E-14004 Cordoba, Spain

October 1995
Vol. 72 No. 10
p. 947
Abstract
The quality of analytical results frequently requires assessment, which has fostered treatment of this subject in a host of chemical books for students. Accordingly, new experiments need to be devised in order to help students adapt to it. This paper presents a straightforward exercise to demonstrate how quality control and the analysis of variance technique are implemented in practice. The exercise also is attractive because the analyte (chlorophyl) is determined in real samples (plants) that students can collect by themselves. In this way, they can realize the significance of sampling and learn how to do it properly.
