Troubleshooting
PurIon temperatures are stabilizing.
[r] seconds remain. (where [r] is a number)
The PurIon vacuum level is too low to operate. Please
verify that the roughing pump is on and operating cor-
rectly.
Pirani Pressure: [s1] mbar. (where s1 is the vacuum read-
ing).
The PurIon has been shut down. It will be unavailable for
use until the NextGen has been rebooted. Please ensure
the PurIon and fluid interface are both turned on before
rebooting the NextGen.
The splitter valve seals have exceeded their recom-
mended life. The PurIon will continue to operate, but
there is an increased possibility of leakage at the splitter
valve and loss of PurIon detection during a separation.
No ion source is detected on the PurIon. Please ensure
that the ion source is properly installed and connected. If
the source is still not detected, contact a qualified service
technician. Error 309

1. Ensure that the O ring seals are in position.
2. Place the capillary inlet cone into the opening and press
down until the threads are able to engage. There may be
slight restriction in a downward motion as the part is
almost completely inserted. This is the capillary opening
the valve to the vacuum region.
3. Screw the capillary inlet cone into the inlet. Finger tight is
sufficient as long as the part is fully seated.
4. Replace the ion source.
5. Place the PurIon in the operate mode.
If your instrument stops working and the touch panel display is
off, check the line cord connection.
If the line cord is connected properly, check circuit breaker on the
system's rear panel to ensure it is switched to the O
Table 6-1 Common PurIon
Error Codes and Resolutions
The PurIon has several areas with heaters. The software
has a set timer to allow temperatures to come up to oper-
ating conditions. After that time, a separate error is thrown
if the heaters are not within an acceptable band. The
default time is 300 seconds after entering the operate
condition.
During the standby condition most heaters are set to OFF
except the inlet capillary with is set to 50 °C during
standby.
The Pirani pressure must be below 5.5E-3 mbar before
the PurIon turbo pump will operate. If trying to place the
PurIon in operate without turning on the roughing pump,
this message will appear.
This error generally occurs if the user forgets to turn the
roughing pump back on after cleaning the capillary or
changing the pump oil.
This message is displayed after the PurIon has been suc-
cessfully shut down through the S
serves as a reminder that an NextGen reboot will be nec-
essary for the PurIon to be enabled again by the Next-
Gen.
The splitter valve supplier has stated that typical valve life
exceeds 1,000,000 actuations. After that time, there is no
method of determining when it will leak. The valve can be
rebuilt using the valve rebuild kit (P/N:60-5234-629) or
continue to use and monitor for leakage. Leakage should
not drip out the bottom of the fluid interface front cover.
The PurIon has reported that the ion source high voltage
cable is not properly plugged into its socket. This is the
cable with the round connector and is to the right and
behind the ion source.
This generally occurs upon changing or cleaning probes.
