6.7.4 Signal Channels
The following signal channels are available for the detector:
•
CAD_1
The signal channel is available for data acquisition.
•
Background current
The signal channel displays the background current of the detector
during data acquisition without autozero or filter constant applied.
It is recommended to always record the background current signal
channel.
If a problem occurs, the information from the signal channel can
provide helpful information to identify and eliminate the source for
the problem.
•
Gas regulator pressure
The signal channel records and monitors the nebulizer gas pressure
during data acquisition.
It is recommended to record the signal channel for troubleshooting
purposes.
For proper gas pressure regulation, or if baseline noise or poor
precision occurs, the information from the signal channel can
provide helpful information to identify and eliminate the source for
the problem.
• Evaporation tube temperature
The signal channel records and monitors the actual temperature of
the evaporation tube during data acquisition.
It is recommended to always record the evaporation temperature
signal channel for troubleshooting purposes.
If a problem occurs, the information from the signal channel can
provide helpful information to identify and eliminate the source for
the problem.
