X-STREAM X2

1.2 Configuration of Gas Lines

Various materials are available to allow the
analyzer to be customized to your needs.
The materials used are selected based on
the characteristics of the sample gas, e.g.
diffusion rate, corrosiveness, temperature
and pressure.
1.2.1

Materials Used

The physical and chemical properties of the
sample gas as well as the conditions under
which measurement takes place influence the
choice of materials. Among those available
are Viton , PFA and stainless steel.

1.2.2

Safety Filter

The analyzers are generally fitted with an
internal stainless-steel filter. This filter is not
a replacement for any dust filter in the prepa-
ration of the gas, but represents a last line of
defence.
1.2.3

Inlets and Outlets

Rackmounted and tabletop devices are fitted
with PVDF inlets and outlets (ø 6/4 mm) as
standard. Alternatively, Swagelok™ or stain-
less steel fittings (ø 6/4 mm or ¼ in can be
fitted.
Wall-mounted field housings are supplied
with Swagelok™ or stainless steel fittings (ø
6/4 mm or ¼ in) ausgestattet.
Other materials available on request.
X-STREAM X2FD units are always supplied
with flame arrestors and stainless steel fittings
(ø 6/4 mm or ¼ in).
1.2.4

Pipework

Unless otherwise specified, the analyzers
are supplied with Viton
6/4 mm or ¼ in). Other materials (e.g. stain-
less steel) can be used, depending on the
application.

Infallible Containments

Infallible containments are gas lines which,
due to their design, can be regarded as per-
manently technically tight. This is achieved
by, for example, welded joints, or metallically
sealing joints (e.g. tap connectors and bin-
ders), providing they are seldom disconnec-
ted. Gas lines configured in this manner can
be used for measuring noxious, flammable
and explosive gases. At the time of going
to press, infallible containments for thermal
conductivity analysis (TC) are available; other
analysis methods are projected. Further in-
formation about infallible containments can
be found in the separate instruction manual
supplied with these units.
Infallible containments do not
render it unnecessary to test for
leaks regularly, e.g. following
lengthy breaks in service, sub-
stantial alterations, repairs and
modifications.
Read the separate instruction
manual giving detailed instruc-
tions on the configuration, ope-
ration and maintenance of units
fitted with infallible contain-
ments.
