It is difficult to selct the most suitable column for a specific analysis. Therefore we try to help you with the column selection as best as possible. If possible, check the sample applications of the GC manufacturers and accessory suppliers or published application notes beforehand. You can find further information in the column selection brochure of Agilent, the world's largest manufacturer of GC columns.
Choose a stationary phase - the most critical decision - by factors such as selectivity. polarity and phenyl moiety.
The column diameter influences the separation efficiency, the retention of the analytes, the column pre-pressure and the carrier gas flow rates.
The column length of GC columns changes the retention, the column pre-pressure and the column bleed - as well as the costs. The separation capacity is proportional to the column length.
The film thickness of the column has an influence on retention, dissolution, column bleed, inertness and capacity.
