E16-02: Troubleshooting Chromatographic Systems
Dr. Merlin K.L. Bicking, ACCTA, Inc., St. Paul, MN
Dr. Douglas E. Raynie, South Dakota State University, SD
Chromatographic instruments are an integral part of almost every analytical laboratory. While modern instruments are very reliable, chromatographers must still deal with many day-to-day problems (peak shape changes, baseline shifts, retention time problems, etc.) that can arise from the instrument, the sample, or the laboratory. This seminar will provide guidance on identifying the causes of such problems, finding solutions, and preventing future problems. Basic LC and GC components will be discussed, and helpful hints will be provided on how to avoid certain problems and maximize the overall analytical efficiency in the laboratory. Students will learn about general troubleshooting strategies, common symptoms, and common solutions to common symptoms. This seminar provides practical technical information that is not available from any other source.
Students are encouraged to bring examples of problems from their own laboratories for open discussion. This has been one of the most popular courses at EAS over for many years, and regularly receives excellent reviews from participants. Come find out why!
