Description
Deactivated capillary CW with 0,53 mm internal diameter and 25 m length is a specialised capillary accessory for gas chromatography applications. This CW-deactivated capillary column is delivered without a cage and offers an extended inert pathway that helps reduce analyte interaction with active sites on the tubing wall. Carbowax-type deactivation imparts polar surface character, which is advantageous when polar analytes must travel through uncoated capillary sections with more consistent recovery and peak shape. The 0,53 mm internal diameter supports higher sample capacity and stable flow behaviour in GC systems, while the 25 m length provides additional flexibility for longer transfer lines, guard segments, or custom column constructions. Supplied as one piece from manufacturer Macherey-Nagel, the capillary integrates into professional chromatography accessory setups. Net weight is approximately 0,13 kg as packed. Choose this cage-free CW-deactivated capillary when a longer 0,53 mm ID deactivated section is needed for analytical GC sample handling and method development.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about deact. cap., CW, 0,53 mm ID, 25 m
What is this article?
deact. cap., CW, 0,53 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.
