Charged Aerosol Detectors Corona Veo (RS) Operating Manual
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.
ATTENTION—Danger d'explosion ou endommagement de l'instrument
Lors de l'utilisation de tétrahydrofuranne (THF), l'utilisation d'air pour
l'alimentation de gaz peut entraîner un danger d'explosion. Ceci peut
constituer un risque pour la sécurité et la santé, et endommager le
détecteur. Utilisez toujours de l'azote avec le tétrahydrofuranne ou
d'autres solvants hautement combustibles.
CAUTION—Excessive Gas Supply Pressure
An improper or excessive gas supply pressure can lead to an
overpressure in the detector that can cause the safety valve in the
detector to release gas. In extreme cases, the excessive pressure can
cause the gas filters to rupture. 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 you use high-pressure gas cylinders as gas supply, double-check
the regulator outlet pressure to ensure that it is within the gas
supply specifications of the detector. This is especially important
when attaching the gas bottle for the first time and when changing
gas bottles.
•
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.
