GC and GC/MS Frequently Asked Questions

Have you ever had a question about your GC or GC/MS analysis, but it seemed so simple that you thought everyone must already know the answer? We can assure you that you’re not the first nor the last person to ask. In chromatography, the simplest of questions can have the most complex answers. A question about which liner to use can lead to a discussion on the benefits of glass wool versus glass frits. A question about how long a column should last triggers a discussion about the importance of a leak-free system, the maximum temperature limit, proper phase selection, and so on. There’s no such thing as an easy answer, often because the answer always “depends” on many factors.

To help you improve your chromatographic know-how, we’ve compiled a list of some of our most frequently asked questions. These may seem like simple questions but, in reality, they have anything but simple answers.
