Description
GC capillary column ROTI®Cap-5 MS non-polar provides a non-polar capillary phase for gas chromatography in a 50 m format with an inner diameter of 0,20 mm and a film thickness of 0,35 µm. The slightly thicker film relative to thinner-film analogues increases stationary-phase loading, which can be advantageous when higher sample capacity or stronger retention of volatile analytes is desired in GC and GC-MS methods. This geometry supports environmental analysis and broader chromatographic applications where a non-polar 5-type MS-compatible phase is specified. The column is supplied as one piece (approximate weight 0,267 kg) and corresponds to the Carl ROTH ROTI®Cap-5 MS non-polar configuration for this length, bore and film combination. Laboratories performing routine separations can integrate the column into validated instrument methods following standard capillary installation practice. Clear dimensional labelling of length, inner diameter and film thickness simplifies comparison with other ROTI®Cap-5 MS variants when matching column geometry to method requirements.
This article is part of GC capillary columns, in GC columns & accessories.

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