Description
Retention Gap Me-Sil is a fused silica capillary column retention gap for gas chromatography, with an internal diameter of 0,25 mm and a length of 25 m. This FS capillary provides an uncoated transfer segment that supports sample introduction, solvent focusing and protection of the analytical column from non-volatile residues. Supplied as 1 pc with a net weight of 0,16 kg, the Me-Sil retention gap is intended for professional GC setups in analytical and research laboratories. The defined 0,25 mm ID and 25 m geometry from manufacturer Macherey-Nagel facilitate installation as a pre-column or transfer line between injector and separation column. Laboratories working with capillary GC methods can use this retention gap to improve sample transfer consistency across routine and method-development workflows. Belonging to the GC chromatography columns category, the product is suited to standard laboratory configurations that require a Me-Sil FS retention gap of this diameter and length. Compact packaging supports straightforward storage and handling in chromatography laboratories.
This article is part of GC capillary columns, in GC columns & accessories.

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