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 a gold-plated or Siltek-treated seal. Use a stainless-steel seal for analyses of unreactive compounds.
Note: The 1.2 mm inlet seal is recommended when installing two columns using a two-hole Vespel/graphite ferrule.
Features & Benefits
- Available in stainless steel, gold-plated, or Siltek-treated. Gold plating or Siltek treatment provide enhanced inertness versus stainless steel.
