Description
EC 4/3 NUCLEOSIL 100-5 SB is an HPLC guard column designed to shield analytical main columns during liquid chromatographic separations. Measuring 4 mm in length with a 3 mm internal diameter, the cartridge carries NUCLEOSIL 100-5 SB packing in the EC 4/3 geometry and is positioned ahead of the primary column bed. In this role it helps retain particulate matter and strongly adsorbed sample components, reducing fouling of the analytical packing and supporting consistent peak performance over longer sequences. The product is supplied as a pack of three pieces and is specified for use with main columns of 3 mm, 4 mm or 4,6 mm internal diameter. Installation depends on the Column Protection System guard column holder (REF 718966), available separately. Offered by manufacturer Macherey-Nagel, these replaceable EC guard cartridges give HPLC laboratories a practical consumable format matched to NUCLEOSIL 100-5 SB chemistry and common analytical column diameters.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEOSIL 100-5 SB
What is this article?
EC 4/3 NUCLEOSIL 100-5 SB 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.
