• Operate gas chromatography equipment safely and effectively according to standard operating procedures.
• Analyze chromatographic data to determine substance composition and concentration.
• Evaluate the quality of analytical results using calibration standards and control samples.
• Implement troubleshooting techniques to resolve common gas chromatography issues.
• Demonstrate adherence to laboratory safety and quality assurance protocols during gas chromatography analysis.

Target Audience

This course is designed for laboratory technicians, analytical chemists, and quality control professionals who are involved in or responsible for substance composition analysis in industries such as petrochemicals, pharmaceuticals, environmental testing, and food and beverage.

Prerequisites

None — open enrollment

Course Outline

Practicals

Overview

Hands-on practical sessions are essential for learners to gain proficiency in GC operation, method development, and troubleshooting. These sessions allow learners to apply theoretical knowledge to real samples, operate instrumentation, and interpret results under supervision.

Practical Activities

• Practical 1: GC System Familiarization and Injection Techniques — Learners identify GC components, set up a basic method, and perform manual injections of a standard mixture. (8h)
• Practical 2: Method Development and Optimization — Learners develop and optimize a GC method for a mixture of alcohols, adjusting temperature program and flow rate to achieve resolution. (8h)
• Practical 3: Quantitative Analysis of a Spiked Sample — Learners prepare calibration standards, analyze a spiked water sample, and quantify target compounds using external standard calibration. (8h)
• Practical 4: Troubleshooting and Maintenance — Learners diagnose common GC issues (e.g., tailing peaks, baseline drift) and perform routine maintenance such as replacing a septum and liner. (8h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total

Component	Out of	Weight
Practical Assignments (rubric-scored)	100%	30%
Daily Average (multiple choice)	100%	20%
Final Test (multi-answer multiple choice)	100%	50%
Final Total	—	100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

How it works

• Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
• Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
• You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
• If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.

Where to find it

Sign in to the LMS, open your dashboard, and your certificates appear under My Certificates. Each entry has a View / Download button and a print option.
