GC Septa Septa & Plug

1) Description

GC Septa Septa & Plug are designed to meet the special needs of gas chromatography in terms of sample introduction, maintaining seal, high temperature resistance, chemical inertness and preventing contamination. These properties ensure high precision and repeatability of chromatographic analysis.

2)Features

Sample Introduction:

GC septa is designed to mate with the autosampler needle on the chromatograph. When the injection needle passes through the septa, ALWSCI^® GC Septa Silicone Septa can quickly self-seal to prevent sample leakage and air intrusion.

High temperature Resistance:

The injection port in GC analysis usually needs to be maintained at a relatively high temperature. ALWSCI^® GC Septa Silicone Septa is made of silicone material that can withstand these high temperatures without deforming or breaking down.

Chemically Inert:

GC septa is made of silica material and will not react with samples, preventing possible chemical contamination or sample loss.

Multiple puncture resistance:

In the case of multiple injections, septa can still maintain its sealing performance and can quickly seal even after being punctured multiple times by the injection needle.

Prevent contamination:

GC septa can effectively prevent environmental contaminants from entering the sample vial, which is crucial to ensure the accuracy of analysis results.

Pressure Maintenance:

The GC septa helps maintain positive or negative pressure inside the vial, which is necessary for some sensitive analyses.

Compatibility:

The GC plug is often used to close injection vials that are not in immediate use to maintain sample integrity.
