Description
OPTIMA 5 capillary column with 0,32 mm internal diameter, 0,25 µm film thickness and 25 m length is a gas chromatography column for analytical separations. This format combines a 0,32 mm ID with a 0,25 µm film on a 25 m capillary, covering common method requirements for the OPTIMA 5 phase type. The product is packed as one piece for direct use in compatible GC systems. Laboratories select this geometry for routine analysis and method development when a mid-length capillary with moderate film thickness is specified. Manufactured by Macherey-Nagel, the column supplies a clearly defined OPTIMA 5 capillary format for industrial, environmental and research chromatography. The 25 m length balances separation path and analysis time, while the 0,25 µm film supports controlled retention and peak shape under appropriate carrier-gas flows and temperature programs. As a single-unit pack, it is suited to laboratories that require an OPTIMA 5 GC column with 0,32 mm internal diameter, 0,25 µm film thickness and 25 m length for installation in standard capillary gas chromatographs.
This article is part of GC capillary columns, in GC columns & accessories.

Questions about OPTIMA 5, 0.32 mm ID, 0.25 µm, 25 m
What is this article?
OPTIMA 5, 0.32 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.
