Gas Chromatography Troubleshooting Guide

This guide provides detailed troubleshooting tips for common issues encountered in gas chromatography (GC) analysis. It outlines various problems such as poor peak resolution, split peaks, fronting peaks, and no peaks, along with their potential causes and solutions. For example, poor peak resolution may arise from a non-selective stationary phase or incorrect analytical conditions, while split peaks can result from mismatched solvent/stationary phase polarity. The guide emphasizes the importance of verifying temperature programs, flow rates, and sample loading capacities. Additionally, it addresses issues like broad peaks, tailing peaks, carryover, and changes in response, detailing specific causes and corrective actions. The document also includes basic steps for isolating problems, such as checking power supply and signal connections, and stresses the importance of documenting troubleshooting steps to facilitate future problem-solving. Overall, this guide serves as a comprehensive resource for effectively diagnosing and resolving GC-related issues.
