Description
EC 250/4 NUCLEOSIL 100-5 Protect I is an EC HPLC separation column intended for analytical liquid chromatography. It provides a column length of 250 mm with an internal diameter of 4 mm and is delivered as one piece per pack. The NUCLEOSIL 100-5 Protect I phase designation defines the stationary-phase chemistry of this packing for HPLC separations that specify Protect I media. EC column hardware suits conventional HPLC systems used in research, quality-control, and method-development laboratories. The 250 mm × 4 mm geometry corresponds to a widely used analytical format for isocratic and gradient work. This column comes from manufacturer Macherey-Nagel and supports professional chromatography workflows that require a defined NUCLEOSIL 100-5 Protect I EC column. Individual packaging simplifies installation, spare-column stocking, and instrument setup. Net weight is 0,28 kg per unit. Choose the EC 250/4 NUCLEOSIL 100-5 Protect I model when protocols call for this length, internal diameter, and Protect I phase combination on standard HPLC equipment.

Questions about EC 250/4 NUCLEOSIL 100-5 Protect I
What is this article?
EC 250/4 NUCLEOSIL 100-5 Protect I 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 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.
