LE0170 : GC Troubleshooting & User Maintenance (Gas Chromatography)

This practical and highly-interactive course
includes practical sessions and exercises
where participants will visit the laboratory and
they will be introduced to various lab
instruments and gas chromatography process.
Practical sessions will be performed using one
of the lab equipment in order to apply the
theory learnt in the class.
This course is designed to provide participants with
a detailed and up-to-date overview of GC
Troubleshooting & User Maintenance (Gas
Chromatography). It covers the components of a
GC system and types of GC configurations; the
principles of gas chromatography, carrier gas
systems and GC columns and stationary phases; the
sample introduction techniques, basic chromatogram
interpretation and inlet, column, detector and gas
system maintenance; the temperature calibration
verification, heating element troubleshooting,
temperature programming optimization; and the
cooling system checks.
Further, the course will also discuss the
autosampler maintenance; the syringe cleaning and
replacement, alignment and calibration, preventing
carryover and routine inspection procedures; the no
peaks / low signal, peak tailing, peak fronting,
baseline noise and drift and retention time shifts; the
contaminated syringe or inlet, residual sample in
column, autosampler carryover issues; and the
improper cleaning protocols.
During this interactive course, participants will learn the resolution improvement,
sensitivity optimization, method development and complex troubleshooting strategies; the
detector-specific issues comprising of FID flame problems, TCD thermal balance issues,
ECD contamination sensitivity and MS interface troubleshooting; the preventive
maintenance planning, quality assurance and control, safety in GC operation and good
laboratory practices (GLP); the system performance tests, detector response verification,
column efficiency checks; and the final system readiness checklist.
