A
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

)
22
CF
3
, molecular weight 1238.18, melting point 190
ºC
).
You can perform a similar experiment using your compound.
