Description
EC 4/3 NUCLEODUR 100-5 C8 ec is an HPLC guard column designed to shield analytical main columns during liquid chromatography. Measuring 4 mm in length with a 3 mm inner diameter, it is specified for main columns of 3 mm, 4 mm or 4,6 mm ID, intercepting particulates and strongly retained sample constituents ahead of the analytical bed.
This article is part of HPLC columns, in HPLC columns & accessories.
The packing employs the NUCLEODUR 100-5 C8 ec stationary phase for reversed-phase separations on octyl-bonded silica. Delivered as a pack of three pieces from manufacturer Macherey-Nagel, the cartridges require the Column Protection System guard column holder (REF 718966) for correct mounting in EC-format systems. This setup supports standard and intermediate-bore HPLC methods where protecting the main column preserves efficiency, reduces fouling, and extends usable column lifetime under routine sample throughput.
Applications span method development, routine quantitative analysis, and quality-control laboratories that need reliable precolumn protection without altering the intended selectivity of the NUCLEODUR C8 ec phase on the analytical column.

Questions about EC 4/3 NUCLEODUR 100-5 C8 ec
What is this article?
EC 4/3 NUCLEODUR 100-5 C8 ec 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?
