Using the ECD
WARNING
To ensure that removable radioactive contamination on the external
parts of the ECD remains at a safe level, the U.S. Nuclear Regulatory
Commission requires that the ECD be wipe tested at least once every 6
months. A record of the results must be maintained for NRC inspection
for a period of three subsequent years.
In Canada, the ECD must be wipe tested at least once every twelve
months and a record of the results must be maintained for AECB
inspection for a period of three years.
WARNING
Do not open Explorer or remove the ECD. If the ECD must be
removed from the instrument contact INFICON.
Operation of ECD is fully automated. This includes setup and operation of the ECD.
The only setup required is to vent the detector and ensure the detector has been
selected for operation. Switching the column effluent to the ECD from the PID is
done with the SETUP key. You do not need to open the instrument in order to setup
the ECD.
Your method will determine the detectors that are in use. Your method may require
the PID and the ECD, the ECD only or the PID only. If the ECD is used as part of
the assay,
Explorer will set the temperature and adjust the valve settings to direct
the column effluent to the correct detector. This will be done when the assay is
downloaded to the instrument.
If you need to develop your own method, you can select the ECD, PID or both,
as described in Selecting Columns and Detectors on page
187.
