Description
GC capillary column ROTI®Cap-5 is a gas chromatography capillary column with a length of 50 m, an inner diameter of 0,20 mm and a film thickness of 0,35 µm. Combining a long narrow-bore path with a somewhat thicker film, this configuration supports analytical GC separations where retention and capacity need to be balanced against efficiency. It is relevant for environmental analysis and other chromatography applications that depend on capillary gas chromatography. Supplied as one piece with a listed weight of 0,267 kg, the column is intended for laboratory GC systems requiring a 50 m × 0,20 mm geometry and 0,35 µm film. Method development and routine monitoring groups can specify this ROTI®Cap-5 variant when those dimensions match validated or developing methods. The product is available from manufacturer Carl ROTH and is oriented toward gas-chromatography workflows in analytical laboratories. Explicit length, diameter and film-thickness data allow confident selection against instrument and method requirements. Single-unit packaging keeps ordering simple for installation or spare-column stock.

Questions about GC-Capillary column ROTI®Cap-5, L 50 m, inner Ø 0.20 mm, thick 0.35 µm
What is this article?
GC-Capillary column ROTI®Cap-5, L 50 m, inner Ø 0.20 mm, thick 0.35 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.
