Description
Retention gap Me-Sil with 0,25 mm internal diameter and 10 m length is a fused-silica capillary column segment for gas chromatography. This FS retention-gap capillary uses Me-Sil deactivation to create an inert, methyl-silylated surface that supports focusing and transfer of analytes ahead of the analytical column, helping protect the main phase and improve injection performance. With an internal diameter of 0,25 mm, the tubing matches common narrow-bore GC column formats and is suitable for coupling as a retention gap or guard section in capillary GC systems. The 10 m length provides a practical working segment for method setup, on-column or splitless injection strategies, and routine laboratory configurations. Offered as a single piece from manufacturer Macherey-Nagel, it belongs to the GC chromatography column accessory range used in analytical laboratories. Net weight is about 0,16 kg as packed. Select this Me-Sil retention gap when a defined 0,25 mm ID fused-silica deactivated segment of 10 m is required for reliable GC sample introduction and column protection.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about Retention Gap Me-Sil, 0,25 mm ID, 10 m
What is this article?
Retention Gap Me-Sil, 0,25 mm ID, 10 m is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in GC capillary columns, inside GC columns & accessories, in Chromatography equipment.
A GC capillary column is specified by the phase, the length, the internal diameter and the film thickness. A thicker film retains longer and takes a higher load. A narrow bore gives sharper peaks and needs a cleaner sample. The maximum temperature of the phase is a hard limit.
A GC capillary column is a long open tube with a stationary phase coated on the wall. The sample is a vapour, carried by gas. The phase, the film thickness, the length and the internal diameter decide which compounds separate and how long it takes. A liner is the glass sleeve in the injector. It is a consumable: it collects the non-volatile dirt. The septum and the syringe are the other parts that leak or shed. Compound identity sits on PubChem under IUPAC names.
