Sample Line Connection; Configuring The Dryer (Optional) - Markes International UNITY-Air Server-xr Installation Manual

Sample line connection

Sample lines are connected to the
1/8" fittings on the front of the Air
Server-xr (8 channel model shown
opposite).
The lengths of 1/8" PTFE tubing
included in the Air Server-xr shipping
kit can be used for sample connection
(cut to required lengths).
NOTE: The Air Server-xr accessory is
only rated to 50 psig. Standards or
samples at pressures higher than this
must be regulated to lower pressures
using appropriate pneumatic controls
before they are connected to an inlet
on the Air Server-xr.

Configuring the dryer (optional)

The Markes International dryer incorporates a semi-permeable membrane which selectively eliminates
water and polar organic compounds from a gas or air stream. The selectivity of the dryer is, sometimes, an
advantage, for example when monitoring multiple trace level hydrocarbons in real-time in ambient air
using GC and FID.
The nafion dryer assembly is shown
opposite.
