Don’t Get Carried Away by Carryover: Troubleshooting GC Chromatography

Have you ever seen analyte peaks show up in a blank, or extra peaks suddenly appear out of nowhere?

It is likely that you have some carryover or contamination in your system. Contamination that creates ghost and carryover peaks can be introduced at different points, including sample preparation, introduction, and separation. The additional peaks can cause false positive identifications and/or inaccurate quantitative results.

Join us as we discuss the most common sources of carryover and how to address them.
