Description
Retention Gap Phe-Sil is a fused silica (FS) capillary retention gap with an internal diameter of 0,25 mm and a length of 10 m for gas chromatography. This Phe-Sil type FS capillary segment serves as a retention gap in GC column trains, providing a defined uncoated intermediate length for sample introduction paths and coupling to the analytical capillary. The 0,25 mm ID and 10 m length give a compact geometry suited to configurations that specify a narrower-bore Phe-Sil retention gap. Delivered as 1 pc, the article has a net weight of 0,13 kg and is presented for straightforward laboratory storage and installation. It comes from manufacturer Macherey-Nagel as part of the GC chromatography columns assortment and is positioned for chromatographic workflows that call for a Phe-Sil retention gap rather than a stationary-phase-coated analytical column. Analysts and method developers can integrate this FS capillary wherever instrument or method documentation requires a 0,25 mm internal diameter Phe-Sil retention gap of 10 m. Bore and length are taken directly from the manufacturer description to keep ordering and system matching unambiguous.
This article is part of GC capillary columns, in GC columns & accessories.

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