Abstract

Modern laboratories, be they in government or industry, operate under strict quality assurance and quality control (QA/QC) guidelines. Yet, these topics are rarely covered in undergraduate laboratories, or are presented as isolated experiments. This fosters the false idea that QA/QC is a separate subject when in actuality it is an integral part of analytical chemistry. It is possible to incorporate QA/QC into existing student laboratories by utilizing blanks, replicates, knowns and spiked samples. Proper use of QA/QC, coupled to an understanding of fundamental chemical principles and statistics strengthens traditional laboratory exercises. Concepts of accuracy and precision are transformed from abstractions into concrete data, and student skills in troubleshooting and problem solving are enhanced.
