Description
OPTIMA 17, 0,25 mm ID, 0,25 µm, 25 m is a capillary column for gas chromatography with a defined internal diameter of 0,25 mm, a film thickness of 0,25 µm and a column length of 25 m. These dimensions establish the chromatographic geometry for GC work where an OPTIMA 17 phase on a 25 m capillary format is specified. The product is supplied as a single column per pack (1 pc), matching the stated unit quantity for straightforward stock and instrument assignment. Internal diameter, film thickness and length are stated together so method parameters can be checked against the installed column without ambiguity. Net weight of the packed unit is 0,25 kg according to product data. The column is offered from manufacturer Macherey-Nagel within the OPTIMA 17 capillary range for GC chromatography laboratories. Selection of the 0,25 mm ID and 0,25 µm film combination over 25 m supports consistent replacement or setup when that exact geometry is required. Packaging is arranged for one capillary column ready for laboratory use. Clear dimensional labelling of ID, film thickness and length helps align the column with existing GC methods and spare inventories.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about OPTIMA 17, 0.25 mm ID, 0.25 µm, 25 m
What is this article?
OPTIMA 17, 0.25 mm ID, 0.25 µm, 25 m is the article on this page. Luminix Health distributes Macherey-Nagel 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.
