ANSWER
The Resolving Quadrupole has an initial value of 4.7, which allows monoisotopic ions + 3-5 Da to pass through the quadrupole.
By increasing this value to a large number such as 15, only monoisotopic ions are allowed to pass through.
Although increasing this value increases the selectivity, but the sensitivity will decrease.
Therefore, it is necessary to consider about the optimum value when for quantitative purpose.
