ADVANCED GAS CHROMATOGRAPHY (GC) OPERATION, CALIBRATION, TROUBLESHOOTING AND PRACTICE MAINTENANCE

The purpose of this course is to provide advance training in gas chromatography techniques and demonstrate their application to practical industry and laboratory problems. The course covers: major components of a gas chromatography; operating principles; calibration methods; preventative maintenance; troubleshooting methods; quantitative methods; set-up procedures; and failure modes for each, along with practical examples. Preventative maintenance is also covered with an emphasis on analysis and troubleshooting methods. The course discusses many other aspects such as optimization of column lengths, flows and temperatures, with the necessary theoretical information in each part. The aim of this course is to enrich and advance the skills and knowledge of the participants and to teach them gas chromatography operation and techniques.
