Description
EC 4/2 NUCLEODUR C18 Gravity-SB, 1,8 µm is an HPLC guard column for protecting narrow-bore analytical columns in high-performance liquid chromatography. The cartridge has a length of 4 mm and an internal diameter of 2 mm, packed with NUCLEODUR C18 Gravity-SB material at 1,8 µm particle size. It is supplied as a pack of three pieces and is intended exclusively for main columns with 2 mm internal diameter. Use requires the Column Protection System guard column holder (REF 718966), available separately. By capturing particulates and highly retained matrix components upstream of the analytical bed, the guard cartridge helps maintain peak shape, retention stability and column lifetime in demanding reversed-phase methods. The Gravity-SB C18 chemistry supports modern UHPLC- and HPLC-style separations on matching NUCLEODUR main columns. This EC-series accessory from manufacturer Macherey-Nagel fits laboratories that standardise on 2 mm ID column hardware. Net weight per pack is 0,02 kg. Select this 4 mm × 2 mm format when a NUCLEODUR C18 Gravity-SB, 1,8 µm guard column is specified for narrow-bore column protection.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR C18 Gravity-SB, 1.8 µm
What is this article?
EC 4/2 NUCLEODUR C18 Gravity-SB, 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.
