Cross disc inlet seals are ideal for high-flow split applications >500 ml/min on Agilent 5890 GCs.

• Siltek® treatment provides inertness similar to fused silica

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, Siltek® or gold-plated seals are recommended.
