Hi all
I am wanting to draw on everyones wisdom again, and apologies if this has been discussed before. I have used the search function and couldn't find anything on it.
I was just interested in what peoples philosophy is for the two different modes. I know some purely use integral for everything and rely on interference corrections to get rid of their higher order overlaps, and some use a combination of both integral and differential. I am about to set up a monazite method again (using Julien Allaz great pdf). In the past we used differential mode for a lot of the elements in our monazite method, and was wondering if this is still the case for the most part?
Cheers
There is no downside to using differential mode as long as you leave the baseline and window "loose". On the Cameca instrument that would be 0.5 for the baseline and 4 or so for the window (9 or so for JEOL instruments).
The advantage is reduction of higher order interferences like 2nd order sodium K-alpha on oxygen.
