Your question is a bit cryptic. Could you give us some details on what you are trying to do?

That does *not* constitute details! Wea re not mind readers.

What instrument? What column & conditions (flow, temperature program, injection volume, etc.). How are you prepping the sample? How much are you injecting? what data system are you using?
