Description
OPTIMA 240 is a GC capillary column with 0,25 mm internal diameter, 0,25 µm film thickness and 30 m length for gas chromatographic separations. The mid-polarity OPTIMA 240 phase and thinner film suit applications that benefit from different selectivity relative to non-polar phases, while the 30 m format keeps analysis times practical for routine laboratory work. Delivered as one piece, the column integrates with standard capillary GC instruments used for method development, quality control and research. Narrow-bore geometry with a 0,25 µm film supports efficient peak shapes for a broad range of analytes under typical temperature-programmed conditions. Produced by Macherey-Nagel, this capillary column provides defined dimensions for laboratories that specify OPTIMA 240 chemistry together with 0,25 mm ID and 0,25 µm film. Select this 30 m configuration when your GC methods require the OPTIMA 240 stationary phase in a compact, widely used column length.

Questions about OPTIMA 240, 0.25 mm ID, 0.25 µm, 30 m
What is this article?
OPTIMA 240, 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.
