Description
PERMABOND CW 20 M capillary column is a gas chromatography capillary column with an internal diameter of 0,32 mm, a film thickness of 0,25 µm and a length of 60 m. This PB CW 20 M configuration is supplied as a special manufacture item and provides the stated geometry for GC applications that call for a longer CW 20 M-type PERMABOND capillary. The 0,32 mm ID together with the 0,25 µm film and 60 m length define the separation path used for instrument installation and method setup. Each pack contains one column intended for analytical laboratories working with standard gas chromatographs. The product comes from manufacturer Macherey-Nagel as part of its GC chromatography column portfolio. Packaging information lists a net weight of 0,28 kg. Laboratories choose the 60 m version when extended column length is specified while keeping the same internal diameter and film thickness as shorter PB CW 20 M formats. Clear dimensional data support method documentation, column replacement and transfer between instruments that require a PERMABOND CW 20 M capillary of these dimensions.
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, 60 m
What is this article?
PB CW 20 M, 0.32 mm ID, 0.25 µm, 60 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.
