Description
EC 250/4.6 NUCLEODUR 100-3 is an EC HPLC separation column built for analytical liquid chromatography applications that benefit from extended bed length. The column measures 250 mm in length with an internal diameter of 4,6 mm, offering additional theoretical plates compared with shorter formats while remaining compatible with conventional HPLC systems. It carries the NUCLEODUR 100-3 designation and is delivered as one piece for direct instrument mounting. Laboratories employ 250 mm × 4,6 mm EC columns when higher resolution or longer retention windows are required for complex sample matrices in research, quality control and routine analysis. Stable EC end-fittings support reliable connections under typical analytical pressures during isocratic and gradient elution. This column is produced by Macherey-Nagel and suits pharmaceutical, environmental, food and industrial chemistry workflows that standardise on 4,6 mm ID hardware. Supplied as a single unit, the EC 250/4.6 NUCLEODUR 100-3 column simplifies method transfer between instruments that already use the same length and diameter. Clear dimensional labelling aids inventory management and helps analysts select the appropriate geometry for demanding separations without altering established system plumbing.

Questions about EC 250/4.6 NUCLEODUR 100-3
What is this article?
EC 250/4.6 NUCLEODUR 100-3 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC columns, inside HPLC columns & accessories, in Chromatography equipment.
An HPLC column is specified by the stationary phase, the particle size, the length and the internal diameter. A C18, 5 µm, 150 × 4.6 mm column is a different article from a C18, 3 µm, 100 × 2.1 mm column. The smaller bore belongs on a lower flow. A column has a direction and a pH range.
An HPLC column is a tube packed, or coated, with a stationary phase. The sample is carried through it by a liquid, and the compounds leave at different times. The phase, the particle size, the length and the internal diameter decide the separation. A guard column is a short sacrificial piece in front of the analytical column. Fittings and tubing have a bore that either preserves the peak or smears it. Compound names follow IUPAC. Data are on PubChem. Method grades often cite the European Pharmacopoeia or USP.
