Description
EC 4/3 RESOLVOSIL is an HPLC guard column intended to protect analytical main columns in liquid chromatography. The cartridge has a length of 4 mm and an internal diameter of 3 mm and carries the RESOLVOSIL stationary phase in the EC 4/3 format. Placed upstream of the separation column, it helps retain particulates and strongly adsorbed matrix constituents before they reach the primary bed, supporting more stable system backpressure over successive injections. The geometry is specified for main columns with 3 mm, 4 mm or 4,6 mm internal diameter and must be installed in the Column Protection System guard column holder (REF 718966). Supplied as a single-piece pack from manufacturer Macherey-Nagel, this precolumn suits routine HPLC protection in pharmaceutical, environmental and chemical laboratories that already run RESOLVOSIL-based methods. Matching the guard phase to the analytical column reduces early contamination of the main bed and can extend usable column lifetime without changing the established separation chemistry. The compact EC 4/3 design integrates into common narrow-bore and standard-bore HPLC setups wherever a short inlet cartridge is preferred for column safeguarding.

Questions about EC 4/3 RESOLVOSIL
What is this article?
EC 4/3 RESOLVOSIL 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.
