I am using an Agilent 5973N GC/MS to detect octane in dichloromethane.
My octane concentration is 1 mM.
The GC method is as follows
-0.1 uL splitless injection
-Solvent delay of 2 mins
-Hold at 40C for 2 mins
-Ramp up to 310C @ 15C/min
-Hold at 310C for 2 mins
With the above method, the octane just barely makes it onto the chromatogram at an elution time of ~3.5-4 mins.
Is there way to make the octane appear later on the chromatogram? For example, would decreasing the ramp rate to 5C/min help?
Thanks!
