Are we able to run "He" and "no He" in the same batch?


1. we recently test As, Cd, Zn, Pb, Ni and Al together, and found Al has small counts under He mode. 

2. we are trying to use " no He' mode for Al, and "He" for another elements to remove interference.  but I am quite confused about the instrument setting because it seems we can use "He" and "no He" under the same batch (see the below picture). 

Does it mean that the instrument will run "No He" first for all the elements, then run "He" for all the elements again? therefore we will have two set of data after the batch finishes?

or we can set No He only for Al,  and He for other elements. finally we only have one set of data in which Al is tested under No He, while others are under He?  if the instrument run in this way, how does it tune? 


Thank you 

best regards,
