The order of peaks in gas chromatography is related
Thread Content
I would like to ask the experts: For the same material, under identical testing conditions and with the same chromatography column, will changing only the initial temperature of the programmed temperature rise result in a change in the order in which the peaks appear? ? ?
No! The initial temperature affects the peak time of low-boiling compounds and the degree of separation, right? The order of peak emergence will not change.
No! The order of peak emergence will not change.
By examining common applications, it can be seen that merely changing the initial temperature of the program heating will result in a change in the retention time of the components with lower boiling points; however, the order in which the peaks appear generally remains unchanged, but it can cause the two peaks to overlap.
No! The retention times of the components change, but the order of peak appearance remains unchanged. Because the valve switching time remains unchanged.
