Detectors
This section contains an illustrated parts breakdown for each of
the following GC detectors and related components.
Flame Ionization Detector ( 316) (FID)
Thermal Conductivity Detector ( 324) (TCD)
Microcell Electron Capture Detector ( 331) (uECD)
Nitrogen Phosphorus Detector ( 339) (NPD)
Flame Photometric Detector ( 347) (FPD)
Note:
The GC 7820A detectors have been redesigned and updated to
new version in Jul 2012. Below are the main changes:
1. The UEPC has been replaced by 5 dedicated detector EPCs.
2. The connections between detector and EPC have been
changed from thumb nuts to tubing blocks similar to 7890.
3. The frit constants update is NOT required for the new version
detectors.
4. The new version detectors require firmware revision
A.01.12.003 or higher.
5. The 7890A detectors (including EPC) and 7820A new
detectors (including EPC) are NOT compatible.
All the old versions of detectors and UEPC will continue to be
supported.
For detail information refer to service note 7820A-035.

How to replace the old version uECD for customer
7820 old version uECD is not an orderable part. If customers
are experiencing failures on 7820 old version uECD and the
uECD cell must be replaced, the new version uECD (P/N
G2397-60620) and two unions (P/N 0100-0124) can be
ordered for uECD cell replacement. Refer to below for parts
required and replacement procedure.

1 Cut anode purge and make-up gas tubes between thumb nuts and old version uECD body. See below figure.
2 Uninstall old version uECD body from GC. 3 Cut two tubing blocks for anode purge and makeup from the
new version uECD, P/N G2397-60620.
4 Install new version uECD body without tubing blocks on GC
334
Agilent 7820 GC Service
Use two unions, P/N 0100-0124, to connect the open end of the new uECD tubing to the open end of the gas tubing coming from thumb nuts. When connecting two unions, avoid to mix anode purge and makeup gas.

Agilent 7820 GC Service
Install NCT to 7820A FID (For old version detector) 1. Cut FID makeup+hydrogen tubing between the "T" connector
and FID body. 2. Cap the open end of the makeup+hydrogen tubing from the
FID body using union 0100-0124 and stainless rod 07680-81150.
3. Cut the nickel catalyst mix weldment from the NCT assembly. 4. Use a union, 0100-0124, to connect the open end of the NCT
input tubing to the open end of the makeup+hydrogen gas tubing coming from the T fitting.
5. The mixed makeup+ hydrogen gases now flow from the FID "T" fitting into the nickel catalyst. Only air flows directly from the UEPC into the FID.
