Using the Direct Sample Probe
With the direct sample probes (direct insertion probe and direct exposure probe) you can
introduce compounds directly into the ion source without GC column separation. This
chapter covers, step-by-step, a direct insertion probe (DIP) experiment using
perfluorotetracosane (CF
3
(CF
2
)
22
CF
3
, molecular weight 1238.18, melting point 190 ºC).
You can perform a similar experiment using your compound.
Creating an Instrument Method
An instrument method contains the settings that the TSQ Quantum XLS Series mass
spectrometer uses during an experiment. Use the Instrument Setup view to create the
instrument method.
Y To create an instrument method
1. On the Thermo Xcalibur Roadmap, click the Instrument Setup icon to open the
