Quantitative Analysis of APC Tablets Several articles appearing recently in THIS JOURNAL have stressed the importance of making laboratory work more relevant to everyday experience. We have had considerable success wibh an analytical experiment which mes a commercial xylene sample' as an unknown, and which uses several different techniques to analyze the sample quantitatively. ltecently we have introduced a similar series of experimenbs in the analysis of APC samples. The primary instrumental techniques used are ~ l t r a v i o l e t infrared,a ,~ and proton magnetic resonance spectruscopy.' The student not only works with a sample with which he is familiar fmm everyday experience, but also has the opportunity to compare the various instntment,al methods and techniques. Strident response to the xylene and APC analysis has encouraged us t,o look far other examples of this type which bring the lahorat,orv closer to the real world. HANRAHAN, E. S., J.
