Connect The Gasifier Transfer Line To The Gc; Install The External Filter Unit - Agilent Technologies 8860 User Manual

3 Installation for 8860 GC and 8890 GC

Connect the Gasifier transfer line to the GC

Connect the Gasifier transfer line to the GC
1 Bend the "Sample In" 1/16-inch tubing connected to the gas sampling valve as shown below.
To avoid cold points, the "Sample In" tubing should be as short as possible. If needed, cut the
"Sample In" 1/16-inch tubing with pipe cutting pliers. Ensure that the end of the cutting is
clean, without burrs.
2 Connect the gasifier transfer line and the GC "Sample In" 1/16-inch tubing using the union
(P/N 0100-0124), tighten the two nuts with a 5/16 open end wrench.

Install the external filter unit

The Filter Kit (P/N G3535-60008) is recommended as a prefilter for the Agilent Gasifier. The filter
kit contains Filter Assy (filter body and 7 µm sintered filter element), 1/8-inch SST Tube with
1/16-inch Reducer, UltiMetal Coating SST Tube, and Ferrule Set & Nut.
Whenever possible, remove particulate contaminants from samples introduced to the Gasifier.
Figure 5
Agilent advises replacement of the external filter unit at regular intervals (an orderable sintered
filter element P/N: 3150-0404). To install the sintered filter element, the male part of the Filter Assy
must be hand-tightened into the female part of the Filter Assy, followed by a 1/8 turn with a
9/16-inch wrench. Orient the arrow on the female part of the filter towards the sample inlet. The
following two figures demonstrated the Filter Assy components, how it is installed, and how to
replace the sintered filter element.
