Description
GC capillary column ROTI®Cap-1 non polar is a non-polar gas-chromatography capillary specified at 15 m length, 0,25 mm inner diameter and 0,10 µm film thickness. The thin film and moderate internal diameter favour efficient separations and relatively short analysis times for non-polar analytes in environmental, quality-control and general laboratory GC methods. ROTI®Cap-1 provides a defined non-polar phase for laboratories that standardise on this chemistry across instruments. Supplied as a single piece from manufacturer Carl ROTH, the column is ready for installation in systems that accept 0,25 mm capillaries. Selection of length, bore and film thickness should align with sample volatility, required resolution and detector sensitivity. This format is well suited to method development and routine runs where a thinner film improves mass transfer and reduces bleed relative to thicker coatings, while the 15 m bed length keeps overall run times practical for high-throughput or screening workflows.

Questions about GC-Capillary column ROTI®Cap-1 non polar, L 15 m, inner Ø 0.25 mm, thick 0.10 µm
What is this article?
GC-Capillary column ROTI®Cap-1 non polar, L 15 m, inner Ø 0.25 mm, thick 0.10 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.
