Hi, I am new to ICP-MS, can you please explain to me what P/A factor stands for?
Simply, We could have wide dynamic range by P/A factor in calibration curve.
If it has only pulse mode, its calibration curve is saturated easily.
A pulse range has low concentration(low intensity) and a Analog mode has high concentration(high intensity).
P/A factor is bridge for Pulse and Analog through calculated factor values.
So, In Data analysis program you could check what range(not attached picture).
In DA calibration curve,
Blue point is pulse range.
Pink point is P/A factor range.
Green point is analog range.
