Description
OPTIMA 225 is a capillary gas chromatography column with an inner diameter of 0,25 mm, a stationary film thickness of 0,25 µm and a column length of 30 m. This configuration is intended for GC separations where a narrow-bore geometry and a defined film layer support efficient peak resolution and stable retention behaviour. The OPTIMA 225 phase is widely applied in analytical laboratories for mid-polarity separations of organic compounds in research, method development and routine quality control. Each unit is supplied as one capillary column and fits standard GC instrument setups used in industrial, environmental and life-science workflows. Manufactured by Macherey-Nagel, the column offers clearly specified dimensions that simplify method transfer and column exchange between instruments. The 30 m length provides a practical balance between analysis time and separating power for many routine GC methods, while the 0,25 mm ID and 0,25 µm film support focused, high-efficiency chromatography. Packaging is oriented to laboratory handling and storage of capillary GC columns prior to installation.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about OPTIMA 225, 0.25 mm ID, 0.25 µm, 30 m
What is this article?
OPTIMA 225, 0.25 mm ID, 0.25 µm, 30 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.
