Description
PERMABOND CW 20 M capillary column with 0,25 mm internal diameter, 0,25 µm film thickness and 25 m length is a gas chromatography column designed for analytical GC separations. The PERMABOND CW 20 M phase is delivered in capillary format with a defined film coating that supports reproducible retention for a wide range of polar analytes under standard GC conditions. An internal diameter of 0,25 mm and a film thickness of 0,25 µm provide a balanced combination of efficiency and capacity for routine quantitative and qualitative work. The 25 m column length is a common choice for method transfer, quality control and research applications that require higher resolving power than shorter capillaries. Supplied as a single piece from manufacturer Macherey-Nagel, the column installs directly into compatible gas chromatographs used in chemical analysis laboratories. Select appropriate carrier gas, temperature programme and detection settings to match your validated GC method and sample matrix.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about PB CW 20 M, 0,25 mm ID, 0,25 µm, 25 m
What is this article?
PB CW 20 M, 0,25 mm ID, 0,25 µm, 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.
