Cold spots or active surfaces ( adsorption sites ) in the GC / MS interfacecan causepeak tailing and peak broadening
When wool is forcefully inserted or removed , these scratches can expose active sitescausingpeak tailing and poor reproducibility
Slow transfer of the sample from the injector to the columncausespeak broadening and peak tailing
