Description
GC capillary column ROTI®Cap-5 is configured with a length of 10 m, an inner diameter of 0,25 mm and a film thickness of 0,25 µm for gas-chromatographic separations. The 0,25 mm bore and matching 0,25 µm film provide a balanced geometry commonly chosen for routine capillary GC, offering practical sample capacity alongside efficient resolution of target compounds. This column supports environmental analysis and general chromatography tasks where a short 10 m ROTI®Cap-5 capillary is preferred for faster run times or specific method designs. Delivered as one piece from manufacturer Carl ROTH, it is suitable for installation on standard GC instruments used in analytical and quality-control laboratories. Explicit listing of length, internal diameter and film thickness allows direct comparison with method SOPs and instrument parameters such as carrier-gas linear velocity and injection mode. Laboratories select this variant when a 10 m × 0,25 mm × 0,25 µm ROTI®Cap-5 column is specified for environmental or broader GC applications and dimensional consistency is critical for reproducible chromatography.
This article belongs on GC capillary columns, in GC columns & accessories.

Questions about GC-Capillary column ROTI®Cap-5, L 10 m, inner Ø 0.25 mm, thick 0.25 µm
What is this article?
GC-Capillary column ROTI®Cap-5, L 10 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.
