Hi strob
Looks like you guessed that I was hinting at volume overload! The problem is likely to be the basicity of these compounds. I've seen a number of methods that either use higher pH mobile phase (using ammonium formate) to get better peak shape…

Hello,
As I said in a previous post, the sample prep method object and field items were added in CDS 2.7 to the available report objects. It looks like from your screenshot you have CDS 2.5 installed so those will not be options.

Saturation is reported by ion, not by TIC abundance.
The maximum possible abundance per ion on SQ instruments is approximately 8.4 × 10^6. To stay within the linear range of the electron multiplier it is recommended to be <= 2.0 × 10^6 per ion.
