What are the factors affecting peak tailing in GC ?
When we actually have peak tailing, it is usually caused by the last thing we did, such as:
1) ran a very dirty sample - need to clip column and/or change liner
2) ran a sequence of dirty samples - see above
3) just changed a liner - used wrong liner or active liner/wool or there is a leak
4) just clipped the column - column set too low, usually, in inlet. Could be too high.
5) just clipped the column - ferrule particles in column. Maybe septum bit if you slide one onto your column.
