6.2 Safety Guidelines for Operation
English Version
When operating the detector, pay attention to the following safety
guidelines:
Observe all warning messages and precautionary statements presented
in section 2.3 Safety Precautions (see page 23 ).
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.
NOTICE Pay attention to the following general guidelines:
•
When operating the chromatography system, always set the lower
pressure limit for the pump. This prevents damage resulting from
leakage or from running the pump dry.
• If there is evidence of leakage in the detector, turn off the pump
flow and remedy the situation immediately.
NOTICE Pay attention also to the following specific guidelines for
detector operation:
•
Pump flow without gas flow causes detector flooding.
Verify that the detector gas flow is always turned on before you turn
on the pump flow to the detector. Do not direct pump flow to the
detector without gas flow being turned on.
• Turn on the gas supply and detector gas flow only when the
nebulizer is installed, the components in the gas flow path are
properly connected, and the protective cover of the gas filter
assembly is installed.
• To start detector gas flow and pump flow
Turn on the detector gas flow first, wait at least 5 minutes and only
then turn on the pump flow.
