Description
Retention Gap CW, 0,25 mm ID, 10 m is a fused silica (FS) capillary column supplied as a CW-type retention gap for gas chromatography applications. The capillary has an internal diameter of 0,25 mm and a length of 10 m, dimensions commonly selected when a compact deactivated inlet section is required before the analytical GC column. In capillary GC, retention gaps help with sample introduction, focusing of analytes and shielding the coated phase from non-volatile residues under established laboratory practice. This article is packed as 1 pc for direct use on GC instruments. The FS capillary retention gap from manufacturer Macherey-Nagel is intended for analytical laboratories performing routine and research GC separations that need a defined CW retention-gap segment. Net weight is 0,14 kg, supporting convenient handling and storage. Specifying 0,25 mm ID and 10 m length allows clear matching to method parameters and injector–column interfaces. The product belongs to the GC chromatography column category and is described solely by its stated type, diameter and length for professional laboratory procurement.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about Retention Gap CW, 0,25 mm ID, 10 m
What is this article?
Retention Gap CW, 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.
