Description
EC 4/2 NUCLEODUR SPHINX RP, 3 µm is an HPLC guard column for protecting analytical main columns in reversed-phase liquid chromatography. The unit is 4 mm long with a 2 mm internal diameter and is specified for main columns with 2 mm ID, reducing the load of particulates and strongly retained matrix components on the analytical bed. NUCLEODUR SPHINX RP phase chemistry is suited to reversed-phase HPLC workflows in research, quality control and routine analysis. Each pack supplies three guard columns from manufacturer Macherey-Nagel and must be used with the Column Protection System guard column holder (REF 718966). The EC 4/2 geometry supports narrow-bore chromatography where controlled extra-column volume and dependable precolumn protection matter. Aligning guard-column and main-column phase type assists stable retention and peak shape over extended analytical runs. These cartridges are a practical consumable for laboratories running 2 mm ID HPLC columns with the corresponding column-protection hardware.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR SPHINX RP, 3 µm
What is this article?
EC 4/2 NUCLEODUR SPHINX RP, 3 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.
Which category should I open next?
