Gas Supply
CAUTION—Explosion Hazard or Damage to the Detector
When using tetrahydrofuran (THF), the use of air as supplied gas may
pose an explosion hazard. This can pose a safety and health risk and
damage the detector. Always use nitrogen with tetrahydrofuran or other
highly combustible solvents.
CAUTION—Excessive Gas Supply Pressure
An improper or excessive gas supply pressure can lead to an
overpressure in detector that can cause the detector to release gas. This
can pose a health and safety risk.
•
Observe the gas supply pressure range that is specified for the
detector. Do not exceed the maximum gas supply pressure.
• If the overpressure relief valve is releasing gas as a result of an
overpressure in the detector during operation, turn off the detector
immediately. Remedy the situation as described in the
Resolving Gas
Supply Overpressure
section in this manual.
CAUTION—Gas Filter Rupture upon Excessive Gas Supply Pressure
An excessive supply gas pressure can lead to an overpressure in the
detector and cause the gas filters to rupture. This can pose a health and
safety risk.
•
Turn on the gas supply only when the gas filters are properly
connected to the detector and the protective cover is properly
installed.
•
Observe the gas supply pressure range that is specified for the
detector. Do not exceed the maximum gas supply pressure.
•
Before you start the replacement of the gas filter assembly, make
sure that the gas supply and the detector gas flow are turned off.
