Frequently asked questions

What causes split peaks in Gas Chromatography?

Split peaks are almost always related to the injector or inlet.

How can injection technique affect peak splitting?

Erratic injections can cause split peaks, and using an autosampler can help avoid these inconsistencies.

What should be checked if split peaks occur after installing a column?

You should check to see if you have the right position in the injector.

How can sample volatility issues be identified?

Splitting in later eluting peaks indicates volatility issues, requiring a check of temperatures at the transfer line and detector base.
