Inlet Seals for Agilent GCs, Replacement
- Siltek® treatment provides inertness similar to fused silica.
- All seals include washers.
The inlet seal at the base of the Agilent 5890/6890/7890 GC injection port contacts the sample and must be changed frequently to prevent adsorption of active compounds. In addition, septum fragments and sample residue accumulate on the disk surface, requiring disk replacement.
To reduce breakdown and adsorption of active compounds, use Siltek® or gold-plated seals.
Note: The 1.2mm inlet seal is recommended when installing two columns using a two-hole Vespel®/graphite ferrule.
for Agilent GCs
*0.8mm ID stainless steel inlet seal is similar to Agilent part #18740-20880,
0.8mm ID gold-plated inlet seal is similar to Agilent part #18740-20885.
