Description
GC-Capillary column ROTI®Cap-5 is a gas chromatography capillary column specified with a length of 25 m, an inner diameter of 0,25 mm and a film thickness of 0,50 µm. This narrower-bore format suits analytical laboratories performing environmental analysis and high-resolution GC separations of volatile and semi-volatile analytes. Offered as 1 unit, the column is ready for installation on conventional gas chromatographs used in method development, routine testing and quality control. The ROTI®Cap-5 column from manufacturer Carl ROTH pairs a 0,25 mm inner diameter with a 0,50 µm film to balance efficiency and retention for demanding chromatographic methods. Environmental laboratories, industrial QC departments and research groups can adopt this geometry when protocols call for these precise dimensions. Explicit length, bore and film data support reproducible retention times, straightforward method transfer and reliable day-to-day performance within capillary GC workflows that rely on the ROTI®Cap-5 series.

Questions about GC-Capillary column ROTI®Cap-5, L 25 m, inner Ø 0.25 mm, thick 0.50 µm
What is this article?
GC-Capillary column ROTI®Cap-5, L 25 m, inner Ø 0.25 mm, thick 0.50 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.
