440 TSQ 9000 Hardware Manual
The direct probe controller regulates the temperature of the direct sample probes used to
vaporize solid or liquid samples into the ion source. For details about using a probe controller,
see the Direct Probe System User Guide (PN 1R120505-0006).
There are two types of probes:
• The Direct Insertion Probe (DIP) uses a heated sample cup to introduce sample into the
ion source.
• The Direct Exposure Probe (DEP) uses a heated wire filament to introduce sample into
the ion source.


To install a DIP or DEP

1. Place the direct probe controller on top of or near the TSQ 9000 instrument.
2. Connect the 9-pin cable to the direct probe controller and to the Accessory Start
connector on the left hand sub panel of the instrument.
3. Connect the direct probe controller to the electrical outlet.
4. Connect the DIP or DEP to the direct probe controller with the large gray cable. If you
are using a DIP, connect a suitable supply gas to the compression connector on the direct
probe controller.
Note Before using the direct sample probes, you must remove the ion source from the
instrument and replace the repeller with the repeller supplied in the probe kit. The new
repeller has a hole in the center. Then replace the ion source into the instrument and allow
it time to thermally equilibrate. See the Direct Probe System User Guide for more details.
