42 Operation and Maintenance Manual
Environmental Considerations
The instrument should be operated in an environment which is comfortable
for human habitation with reasonably constant temperature and humidity.
Operation of the instrument at elevated temperatures (>30 °C) may result in
an increased background noise from the photomultiplier tube.
Combustion Gas Requirements
The Agilent 355 SCD and 255 NCD both require a hydrogen source; the 355
SCD requires an air source, and the 255 NCD requires an oxygen source.
Oxygen may be used for the ozone generator in either Detector to obtain a
modest increase in sensitivity; the Dual Plasma Burner was designed for use
