In the first GC columns, gas chromatography phases were simply coated onto the column. This was mostly the case with packed columns, but also the same with the very first capillary columns. Injecting water onto these phases dissolved the phase and caused the phase to elute from the columns.
Guest Author: Ramkumar Dhandapani, Ph.D.- Gas Chromatography Technical Manager In gas chromatography (GC), the separation of analytes is achieved primarily based on boiling point (Van der Waal’s interaction), although other intermolecular Continue Reading
You’ve worked so hard crafting the perfect costume, decorating your home, and sneaking chocolate from your kids, we decided to treat you to the best technical guides this Halloween.
Depending on method conditions, early eluting compounds are apt to have poor peak shapes. Within are some steps that can be implemented to help minimize any distortions to early eluting peaks in gas chromatography.
The boiling point is the temperature where liquid has enough energy that molecules transferring into the vapor phase exert a pressure that is equal to the outside pressure. This allows molecules anywhere—not just the surface—to transfer to the gas phase.
