The analysis of diesel fuel using gas chromatography-mass spectrometry is described. The experiment is especially appropriate for courses in instrumental analysis and environmental chemistry. Results from the injections of small amounts of liquid samples include total-ion- and single-ion-mode chromatograms as well as mass spectra of polycyclic aromatic hydrocarbon derivatives. The calculation of retention indices for programmed-temperature chromatography is illustrated.
Supplement
Experimental procedure, data analysis, laboratory summary, student handout, and other information are provided.
Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
Take JCE along on your outreach missions. Copies of the Journal, guest access to JCE Online, our publications catalog, and more are available for your participants.
