Description
EC 4/3 NUCLEODUR SPHINX RP, 5 µm is an HPLC guard column developed to protect analytical reversed-phase main columns during routine liquid chromatography. The cartridge is 4 mm long with a 3 mm inner diameter and contains NUCLEODUR SPHINX RP packing at a 5 µm particle size. Delivered as a pack of three pieces from manufacturer Macherey-Nagel, these EC precolumns are intended for main columns with 3, 4 or 4,6 mm internal diameter. Correct use requires the Column Protection System guard column holder (REF 718966). Positioned before the analytical bed, the guard column traps particulates and strongly retained contaminants, helping maintain separation efficiency, peak quality and column lifetime. SPHINX RP chemistry supports reversed-phase applications under common laboratory mobile-phase regimes. The EC 4/3 format provides a compact, exchangeable protection element for analytical HPLC systems matched to the stated internal diameters, allowing laboratories to safeguard main columns without altering the established separation chemistry of their methods.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEODUR SPHINX RP, 5 µm
What is this article?
EC 4/3 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.
