Connect the Gas Supply
a supply of filtered, oil-free, dry, and clean gas (nitrogen or air) is required to operate the
eLS detector.
NOTICE
Highly purified gas is not required to operate the ELS detector; however, a good quality of
gas is mandatory for high performance detection. The gas should be free from particles (dust)
and from oil.
WARNING
Fire and explosion hazard.
Do not use a combustible gas with combustible solvents or analytes.
Inspect the supplied tubing for damage after installation and before use. Any damage to
tubing could permit gas to leak into the laboratory.
the gas supply must include a pressure gauge that is stable and regulated by an external
manometer. the eLS detector is typically operated with a gas pressure of 2 bar (29 psi)
and gas consumption of 3 L/min. a gas regulator (sold separately, Pn 21040205) with a
5 µm filter, manometer, and fittings is available for purchase.
to connect the PLC Purification System to the gas supply:
1. Connect a suitable length of clean, 6 mm (oD) tubing from the gas regulator outlet to the
gas inlet (Port a).
2. Connect a suitable length of clean, 6 mm (oD) tubing from the gas source to the gas
regulator inlet.
3. insert the tube into the fitting until it reaches the back, and then pull the tube to check
engagement of the grab.
NOTICE
Ensure that the gas pressure supplied to the detector is less than 4.5 bar (67 psi). If the
pressure increases above 4.5 bar, the pressure sensor may be damaged (not covered by
the warranty).
