The Gas Chromatography Maintenance & Troubleshooting Course gives laboratory and instrumentation professionals a structured, practical approach to diagnosing and resolving the full range of GC operational problems — reducing downtime, improving analytical accuracy, and extending instrument life.
Gas chromatography systems are precision instruments where even minor faults can compromise data integrity, delay analysis, and disrupt laboratory operations. This course equips delegates with a systematic troubleshooting methodology — covering eight problem categories, chromatographic symptoms, detector faults, shutdown conditions, and hands-on troubleshooting tasks.
From baseline problems and peak shape issues to flow and pressure faults, detector malfunctions, and column shutdowns, every common GC failure mode is addressed directly. Delegates also learn how to prevent problems through proper consumable management and instrument self-checks.
This is a course built for professionals who need to keep GC systems running reliably and want the confidence to diagnose and fix problems quickly and safely.
The Gas Chromatography Maintenance & Troubleshooting Course is designed to develop systematic, confident troubleshooting capability across all major GC system components — from chromatographic performance issues to detector, flow, and shutdown faults.
By the end of this course, participants will be able to:
The Gas Chromatography Maintenance & Troubleshooting Course is designed for laboratory, instrumentation, and technical professionals who operate, maintain, or support GC systems and need the skills to diagnose and resolve faults confidently and efficiently.
This course is suitable for:
The Gas Chromatography Maintenance & Troubleshooting Course is delivered through a highly practical, symptom-based learning approach. Rather than covering GC theory in isolation, the course is structured around real fault categories and the step-by-step process of diagnosing and resolving each one.
Delegates work through troubleshooting scenarios progressively — from common chromatographic symptoms through to detector faults, shutdown conditions, and hands-on practical tasks.

Common questions about our training courses
Delegates learn a structured, systematic troubleshooting methodology built around eight defined problem categories. Rather than relying on trial and error, delegates leave with a repeatable diagnostic process — enabling them to identify the root cause of GC faults more quickly, resolve them more effectively, and prevent recurrence through better maintenance practices.
A full day is dedicated to ALS, detector, and communications symptoms — covering FID, NPD, TCD, and FPD detector problems in detail. Delegates learn how to systematically identify detector faults, distinguish between symptom types, and apply the appropriate corrective action for each detector technology used in their laboratory or facility.
Very practical. The final day is dedicated entirely to troubleshooting tasks — including external leak checks, GC leak identification, column flow measurement, detector flow measurement, GC self-checks, and gas purifier replacement decisions. Delegates perform these tasks in a structured learning environment, building the hands-on confidence they need to apply them directly on their instruments.
Delegates will develop the ability to diagnose and resolve a comprehensive range of chromatographic symptoms — including retention time problems, baseline issues, contamination and carryover, peak shape problems, resolution issues, and column faults. These are the most commonly encountered performance problems in GC analysis, and resolving them directly improves data quality and instrument reliability.
Day 4 covers the full range of GC "Not Ready" and "Shutdown" conditions — including flow and pressure problems, temperature faults, detector issues, valve problems, column shutdown, and hydrogen shutdown. Delegates learn how to diagnose each condition safely, understand its root cause, and restore the instrument to full operational status efficiently.
By developing a structured diagnostic approach and building familiarity with the most common fault categories, delegates become significantly faster and more accurate at identifying and resolving GC problems. Combined with the problem prevention and consumable management skills covered in the course, this directly reduces unplanned downtime and the disruption it causes to analytical workflows.
