Description
OPTIMA 1 is a capillary gas chromatography column featuring an internal diameter of 0,25 mm and a film thickness of 0,50 µm with a column length of 25 m. This capillary GC format is intended for analytical laboratories performing gas chromatographic separations that benefit from a mid-range column length combined with a narrow bore and defined stationary film. The 0,25 mm ID supports conventional capillary GC connections and method transfer, while the 0,50 µm film thickness offers a controlled phase loading suitable for many volatile and semi-volatile applications. Available from manufacturer Macherey-Nagel as a single-piece pack, the 25 m OPTIMA 1 column fits routine QC, research, and method-development setups that require balanced resolution and analysis time. Capillary columns of this geometry are commonly integrated into GC systems for qualitative and quantitative work where reproducible film thickness and internal diameter help stabilise retention behaviour. The 25 m length provides additional separating power compared with shorter formats while remaining practical for everyday laboratory scheduling. Delivered as one column per pack, it is ready for installation in standard gas chromatography instruments.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about OPTIMA 1, 0.25 mm ID, 0.50 µm, 25 m
What is this article?
OPTIMA 1, 0.25 mm ID, 0.50 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.
