说明

一般說明

The inlet seal on an Agilent GC must be regularly changed to prevent sample adsorption due to accumulation of sample residue and/or septum fragments. Supelco manufactures replacement inlet seals using a high quality stainless steel plated with pure gold to insure inertness. No brighteners are used in the plating process. This cross design seal is suitable for applications with high split flows (>200 mL/min.). Each pack includes one washer for each seal.

應用

Gold-plated inlet seal may be used in the GC injection port for thermal desorption-gas chromatography/mass spectrometry (TD-GC/MS), where residual accumulation was noticed resulting in analyte adsorption and elevating signal background. Hence, replacing the gold-plated seal in regular intervals decreased the interference.
