Description
VA 21/4 NUCLEOGEL Anion I is a specialised HPLC guard column for anion-exchange workflows. It measures 21 mm in length with an internal diameter of 4 mm and is supplied as a pack of 2 pieces. Used ahead of the analytical column, this precolumn helps retain particulates and strongly retained sample components, supporting stable separation performance and longer analytical-column lifetime. The cartridges are intended for use with guard column holder C (REF 719538), allowing straightforward integration into standard HPLC setups. Manufactured by Macherey-Nagel, the NUCLEOGEL Anion I chemistry suits ion chromatography and related HPLC methods in research, quality control, and method-development laboratories. The short bed length keeps extra-column volume low while still providing effective front-end protection for the main column. Laboratories running routine anion analyses can stock these matched guard cartridges for scheduled replacement without changing the analytical phase. Compact dimensions and a defined two-piece pack size make the product practical for continuous instrument operation and planned maintenance intervals in busy chromatography suites.

Questions about VA 21/4 NUCLEOGEL Anion I, 2 pcs
What is this article?
VA 21/4 NUCLEOGEL Anion I, 2 pcs 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 Chromatographie.
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.
