What is the order of peaks in gas chromatography?
Thread Content
Is it based on different solubilities, or polarity? Can someone explain this in detail?
It’s related to the chromatography column chosen, I guess
The peaks appear in order, from low to high, based on boiling point or flash point.
I think the peaks appear in order of relative molecular mass, from smallest to largest.
Are gas-solid and gas-liquid columns different?
1. Boiling point level 2. Column polarity and product polarity
If it has nothing to do with polarity, then there is only one model of column
Based on the properties of the columns, polar columns and non-polar columns

The capacity factor k is related to temperature; it represents the ratio of the mass of a substance in the stationary phase to its mass in the mobile phase. k directly determines the retention time – the larger k, the later the peak appears； The effect of temperature on the peak emergence time is also achieved by influencing the k value, which in turn changes the peak emergence time; within a certain temperature range, the higher the temperature, the earlier the peak emerges
