g Write this number down.
2 Edit the acquisition parameter file so that the newly determined value will
be applied whenever Data Acquisition starts up and will be used for tuning
and data acquisition:
a Open the D:\MassHunter\instr\default\ folder, and then open the
appropriate .xml file with Notepad:
b Locate the set point for the Collision Cell gas flow between the
<flowrate> and </flowrate> tags. In this example, the set point for the
flow rate is 520:
<cellFlow>
<flowA>1</flowA>
<flowB>0</flowB>
<flowrate>520</flowrate>
</cellFlow>
c Change the flow rate set point to the value that you wrote down as the
optimal flow rate. In this example, the value is changed to 550:
<cellFlow>
<flowA>1</flowA>
<flowB>0</flowB>
<flowrate>550</flowrate>
</cellFlow>
