Instructor: Dr. Brian C. Smith – Big Sur Scientific
Why Take This Course?
This two day (16 hour) online course teaches scientists how to use gas chromatography (GC) and high-pressure liquid chromatography (HPLC) to purify, identify, and quantify chemical species in samples. The course begins with a thorough grounding in chromatographic theory where analysts learn how to optimize their separations. We then launch into a detailed description of GC and HPLC instrumentation so attendees choose the best equipment and separation technique for their samples. The next section discusses how to calibrate chromatographs to insure quantitative accuracy. Students are then introduced to mass spectrometry (MS), perhaps the most important chromatographic detector, and see how GC-MS and LC-MS work. The course wraps up with a discussion of the applications of chromatography that is customized for each class. Current modules include the forensic and pharmaceutical applications of chromatography.
Who Should Take this Course:
Anyone who works in a chemical analysis lab, and uses or wants to use chromatography to purify, identify, and quantify the chemical species in samples.
