Vent the Exhaust Line
the carrier gas containing volatilized mobile phase and analytes exits the detector through
the black exhaust tube. this tube can be cut and should be directed into a fume hood or
exhaust vent.
Vent to Fume Hood
ensure that the fume hood draws gas from the detector, i.e., there is positive pressure
between the detector and the fume hood.
NOTICE
Use a moderate vacuum to avoid turbulence in the nebulization chamber siphon or to prevent
liquid from spilling into the evaporation tube.
Avoid loops or bends in the black exhaust tubing to avoid condensation traps that can result
in poor measurement results.
Negative pressure between the fume hood and ELS detector can introduce contaminants
from the fume hood into the ELS detector.
Connect the exhaust tubing to the fume hood. if necessary, use the two adjustable,
self-adhesive clips supplied to guide the vent tube.
WARNING
Ensure that the vent tube does not become
blocked, bent, or restricted from the detector to
the fume hood.
Avoid long tube installations in an upward
direction, which can create condensation that
flows back into the detector.
NOTE
If an extension line is required because the supplied
tubing is not long enough, a suitable length of 3/4” (ID)
tubing can be fitted over the exhaust tubing.
