Description
PERMABOND CW 20 M is a capillary column for gas chromatography with an internal diameter of 0,32 mm and a film thickness of 0,5 µm. This PB CW 20 M format is supplied at a length of 50 m for use in GC chromatography systems. The column combines a 0,32 mm internal diameter with a 0,5 µm film, dimensions that are clearly specified for method matching and instrument configuration. It is packed as one piece and is intended for laboratory gas chromatography applications where a PERMABOND CW 20 M capillary column of this size is required. Available from manufacturer Macherey-Nagel, the product sits within the established PB CW 20 M series of GC capillary columns. Selection of the 50 m length provides the column bed corresponding to the stated ID and film thickness for routine analytical work. Laboratories can integrate this capillary column into existing GC setups that call for 0,32 mm ID and 0,5 µm film geometry. The catalogue designation PB CW 20 M, 0,32 mm ID, 0,5 µm, 50 m reflects the full dimensional specification of this gas chromatography column.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about PB CW 20 M, 0.32 mm ID, 0.5 µm, 50 m
What is this article?
PB CW 20 M, 0.32 mm ID, 0.5 µm, 50 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.
