Liquid stop LB-1PV and LB-1SS

for protecting gas analysers and gas-phase
chromatographs against liquids

LB-1PV, LB-1SS

Special Features

Sure protection against liquid inrush

Reliable removal of liquid coming
through

Also suitable for high pressures

Available in stainless steel and PVDF

Easy change of the hydrophobic
protective membrane

With wall mounting holder

Application

The M&C liquid-stop LB-1.. is suitable for
protecting analysers against inrush of liquids
out of the gas conditioning unit which is
mounted before the analyser. This avoids
major damages of the analyser.

The most useful position of the liquid stop
LB-1.. is behind the gas conditioning unit,
directly before the flowmeter of the analy­ser.

Description

The hydrophobic protective membrane of
the liquid-stop LB-1.. is placed between the
two parts of the housing which are screwed
together. It is lined with a porous glass filter
frit in order to secure stable proportions.

The pore sizes of the protective membrane
are designed in such a way that gas mole­cules and steam can pass through but liquid
molecules are retained.

The gas inlet and outlet are positioned in
an horizontal line inside the housing. The
liquid outlet shows downwards when being
mounted.

Due to the horizontal flow direction of the
gases and because possible liquids are drai­ning off on the protective membrane due to
its gravity, the leaking through of liquids to
the analyser is avoided.

Eventually occuring liquid can be let off via
a peristaltic pump SR25.1, separator and
automatic liquid drain ADS-SS or a conden­sate vessel TG1 (dip tank). The LB-1 has got a
respective connection possibility.

Changing the membrane is easy to handle.
The optimum positioning of the sealing
O-rings guarantees always a sure sealing of
both housing parts.

The filter inlet and outlet can be turned by
180° on the wall mounting holder so that a
flexible adaption to local circumstances is
possible during mountage.
