5.5 DIP (PCI) Performance test for DIP/5975 MSD Systems
This test uses a traceable standard solution to determine the correct performance of the DIP.
Perform this procedure on both types of probe tips (for liquid and for solid samples).
REQUIREMENTS
- An autotune has been performed.
- A new method for DIP CI measurements has been created in the MS ChemStation
software:
Follow the instructions of the MSD ChemStation manual and note that there are some
different inputs to be made:
• In the menu item “Inlet/Injection Types” select for “Sample Inlet” Other/None, and for
“Injection Source” External Device and enter the value for “Total Runtime” (take the
value displayed in the DIP software minus 1.5 )(see DIP manual)
