Thermo Fisher Scientific has developed a user-friendly tool that provides technical assistance for gas chromatography (GC) methods and applications.

Designed with the expert advice of columnist John Hinshaw, the GC Troubleshooting Guide provides a step-by-step process to easily diagnosis common symptoms. The guide combats difficulties laboratory professionals can encounter when running GC methods: high levels of noise, spiking peaks, ghost peaks, decreasing retention times, and irreproducible results. This tool—offered both as an iPad mobile application and for desktop systems—can help laboratories achieve outstanding performance for routine analyses, utilize advanced capabilities, and increase sample throughput.

Companies in the chemical, environmental, food and beverage, petrochemical, water, and pharmaceutical industries frequently use GC separations in routine analysis and monitoring applications, new product development, production, quality control, and more. By helping laboratory personnel better understand the chemistry behind GC methods, the GC Troubleshooting Guide enables faster problem identification and improved diagnostics. This tool addresses:

• Baseline problems without injection
• Detector problems with injection
• Column and inlet problems
• Problems with results
