Description
EC 4/2 NUCLEODUR SPHINX RP, 1,8 µm is an HPLC guard column intended to protect analytical main columns in reversed-phase liquid chromatography. The cartridge measures 4 mm in length with a 2 mm internal diameter and is specified for use with 2 mm ID main columns, helping retain particulates and strongly adsorbed sample components before they reach the analytical bed. NUCLEODUR SPHINX RP phase chemistry supports reversed-phase separations in routine HPLC method work, quality control and research applications. Each pack contains three guard columns from manufacturer Macherey-Nagel and requires the Column Protection System guard column holder (REF 718966) for correct mounting. The compact EC 4/2 format is suited to narrow-bore systems where low extra-column volume and reliable precolumn protection are important. Matching guard and main-column phase type helps maintain consistent retention and peak shape across analytical sequences. These cartridges integrate into existing HPLC workflows that already use 2 mm internal diameter columns and the corresponding protection-system hardware.

Questions about EC 4/2 NUCLEODUR SPHINX RP, 1.8 µm
What is this article?
EC 4/2 NUCLEODUR SPHINX RP, 1.8 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.
