Description
EC 4/2 NUCLEODUR SPHINX RP, 5 µm is an HPLC guard column configured to shield narrow-bore analytical columns in reversed-phase chromatography. It has a length of 4 mm and an inner diameter of 2 mm, filled with NUCLEODUR SPHINX RP stationary phase at 5 µm particle size. The product is supplied in packs of three pieces from manufacturer Macherey-Nagel and is specified for main columns with 2 mm internal diameter. Mounting requires the Column Protection System guard column holder (REF 718966). Used ahead of the analytical column, the precolumn captures particulates and highly retained matrix components, supporting stable retention, peak integrity and longer main-column service life. SPHINX RP chemistry is suited to reversed-phase HPLC workflows under typical laboratory eluent conditions. The compact EC 4/2 format fits analytical setups that employ 2 mm ID columns, offering a straightforward consumable option for continuous protection of valuable separation media without changing the primary phase chemistry of the method.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR SPHINX RP, 5 µm
What is this article?
EC 4/2 NUCLEODUR SPHINX RP, 5 µm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC guard columns, inside HPLC columns & accessories, in Chromatography equipment.
A guard column is a short column of the same phase as the analytical column, placed in front of it to catch particles and compounds that would stick forever. It is meant to be replaced. A guard of a different phase changes the separation. The holder and the cartridge are often separate parts.
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.
