Chemstation vs. RTE integrator
Posted: Fri Jan 30, 2015 6:48 pm
Short story: Why is the response for each internal and analyte lower (~1/10th) when I switch from Chemstation to RTE, drawing the peak the same way. I thought response was response...
Longer version:
I'm using an oldish version of Chemstation. (D.01.00 - from 2003)
I've found a bit of stuff online from Agilent talking about the differences between these two integrators. The main one seems to be that chemstation allows timed events (which I don't need) and RTE allows setting more complicated filters (which I also don't need). We've always used the Chemstation one, but apparently RTE is reccomended for quantative analysis, which is what I'm doing (8270). I thought I'd try switching, and what do you know, RTE integrates better. By that I mean that I get fewer weird diagonal integrations that cut off half a peak, or lines drawn above the baseline for no apparent reason. (Those things, btw, don't seem to happen as much with the newer Chemstation version I have on my other instruments.) So I like it... but I want to understand what I'm doing before I commit to the change.
