Polar column for BT45i Gas Chromatograph
Can be used for separation of polar volatiles such as methanol and ethanol.
The polar column is suitable for investigations on volatile polar substances. The retention times are quite long. This makes the polar column not suitable for demonstration tests.
The polar column is also sensitive to water vapour from the air. The adsorbed moisture causes the column to become slightly more polar. The retention times and the resolving power will vary slightly depending on the air humidity. The shortest retention times and best separation are obtained with an anhydrous column. The column gives very useful results even at normal air humidity. The column that is delivered is pre-conditioned with 'normal' air (60% RH).
