Frequently asked questions

What is the most reliable method for selecting a stationary phase?

The most reliable method is to consult the large collection of example applications provided by column manufacturers, GC manufacturers and in published literature.

What happens if compound boiling points differ by more than 30 °C?

They usually can be separated by most stationary phases.

What is the recommended starting point for best performance with a wide range of analytes?

Start with the general purpose Agilent J&W Ultra Inert 1ms and 5ms columns to get the lowest column bleed and column activity.
