Course Description:

    The purpose of this course is to provide Fundamental 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 includes also the practical maintenance where the important parts of GC are demonstrated i.e. inject system part, different liner and syringes, maintenance kit, different columns type, TCD, FID, ECD, FPD detectors, and other accessory parts which is variable used.

Who should attend?

     Laboratories chemists and lab technicians in oil fields, power stations, water treatment systems, chemical and petrochemical industries, and in oil refineries, etc.

Curse objectives:

        After completion this course, laboratory managers, staff, and others who might be affected should:

               • To introduce participants to Fundamentals of gas chromatography and how the individual elements interrelate.

               • To be able to competently use methods on a gas chromatograph to produce robust and valid analytical data.

               • To provide a knowledge of gas chromatography operation, maintenance and troubleshooting.

               • To impart the participants advance techniques and knowledge of principles of gas chromatography.

               • To provide knowledge of accessories and consumables required for gas chromatography operations.

               • To provide good laboratory practices for accurate and reliable analyses.

               • To train participants to know how to change and install gas chromatography parts such as inject systems and columns.

               • To familiarize participants with the techniques used in gas chromatography analysis, qualitative and quantitative
