I am having difficulty repeating a method which was run on Sciex QTrap. I
am using Agilent QQQ. I am monitoring 5-10 ions in each time segment. The
quantification did not have enough data points to quantify... Usually when
this happens I need to work on my my chromatography conditions to get more
seperation. But in order to repeat this method, I have to monitor many ions
at each time segment.
I don't know if I made the question clear. Could anyone who used both Qtrap
and triple quad give

just 5-10 ions in each ions should be fine.
But I'm confused by your following questions. If there is not enough points
for quantify, you need either make the scan quicker or make the
chromatographic peak wider.

What scan speed (amu/sec) you used in ABI Q-Trap, and in Agilent Triple Q?
make sure they are in the same range?

把dwell time改改吧 看看你HPLC的锋多宽 50 to 100 ms should be ok

dwell time 是什么呢?一直不理解。
