Description
GC-Capillary column ROTI®Cap-5 is a gas chromatography capillary column with a length of 25 m, an inner diameter of 0,25 mm and a film thickness of 0,25 µm. It is intended for capillary GC separations where balanced film thickness and internal diameter support analytical work in environmental analysis and broader laboratory chromatography. The defined geometry helps laboratories select a column that matches method requirements and instrument configuration. Delivered as one piece weighing 0,274 kg, the column is suitable for straightforward stocking and installation. This ROTI®Cap-5 variant from manufacturer Carl ROTH is characterised by its 25 m length, 0,25 mm ID and 0,25 µm film, enabling clear comparison with other capillary formats. Gas chromatography users can integrate the column into workflows that specify these dimensions for routine or specialised separations. The product serves chromatography laboratories that need a documented capillary column configuration for environmental testing and general GC applications requiring consistent length, bore and film thickness.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about GC-Capillary column ROTI®Cap-5, L 25 m, inner Ø 0.25 mm, thick 0.25 µm
What is this article?
GC-Capillary column ROTI®Cap-5, L 25 m, inner Ø 0.25 mm, thick 0.25 µm is the article on this page. Luminix Health distributes Carl Roth 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.
