Description
PB CW 20 M capillary column is a PERMABOND CW 20 M gas-chromatography column with an internal diameter of 0,32 mm, a film thickness of 0,25 µm, and a length of 30 m. This capillary GC format is intended for polar-phase separations where a defined combination of internal diameter, stationary-film thickness, and column length is required for method transfer, routine quantification, and higher-resolution analyses. The 30 m length supports extended separation paths commonly used in standard GC methods that need greater resolving power while retaining CW 20 M phase characteristics. Supplied as one piece from manufacturer Macherey-Nagel, the column is suitable for laboratory GC systems configured for 0,32 mm ID capillary columns. Explicit specification of internal diameter, film thickness, and length enables straightforward matching to instrument methods and validated protocols. Ideal for analytical and quality-control laboratories that specify a PERMABOND CW 20 M capillary column in the 0,32 mm × 0,25 µm × 30 m configuration for gas-chromatographic work.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about PB CW 20 M, 0.32 mm ID, 0.25 µm, 30 m
What is this article?
PB CW 20 M, 0.32 mm ID, 0.25 µm, 30 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.
