Description
GC capillary column ROTI®Cap-5 is a gas-chromatography capillary column with a length of 15 m, an inner diameter of 0,32 mm and a film thickness of 1,00 µm. The relatively thick stationary-phase film increases sample capacity and retention, which is useful for highly volatile analytes and applications that benefit from stronger interaction with the phase. In environmental analysis and general GC work, this geometry supports separations where thinner films would give insufficient retention. Supplied as a single column from manufacturer Carl ROTH, the ROTI®Cap-5 format is suited to laboratories that require a short, wide-film capillary for screening, headspace-type volatiles or methods needing higher loadability. The specified dimensions—15 m length, 0,32 mm inner diameter and 1,00 µm film—enable clear method documentation and instrument setup. Choose this variant when greater film thickness is preferred over the thinner ROTI®Cap-5 options for your gas-chromatographic workflow.

Questions about GC-Capillary column ROTI®Cap-5, L 15 m, inner Ø 0.32 mm, thick 1.00 µm
What is this article?
GC-Capillary column ROTI®Cap-5, L 15 m, inner Ø 0.32 mm, thick 1.00 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.
