Description
Les précolonnes UHPLC NUCLEODUR® Phenyl-Hexyl assurent une protection optimale pour les systèmes de chromatographie liquide ultra-haute performance. Cette configuration utilise une phase liée phényl-hexyle sur des particules de 1,8 µm dans un corps de 4 x 2 mm et est fournie en paquets de 3 unité(s). La finesse du diamètre des particules est adaptée aux pressions de service et aux régimes de débit de l'UHPLC, contribuant à maintenir l'efficacité de la colonne analytique en aval tout en piégeant les débris et les constituants de l'échantillon fortement adsorbés. La sélectivité phényl-hexyle favorise les interactions π–π et hydrophobes fréquemment exploitées pour les composés aromatiques et modérément polaires. Les dimensions compactes permettent de monter la cartouche de garde dans des supports compatibles sans volume extra-colonne excessif. Ces unités NUCLEODUR® du fabricant MACHEREY-NAGEL sont destinées aux laboratoires qui utilisent déjà des méthodes UHPLC phényl-hexyle et souhaitent prolonger la durée de vie de leurs colonnes analytiques grâce au remplacement régulier des précolonnes. Le paquet de trois unités facilite le fonctionnement continu et la maintenance programmée dans les environnements chromatographiques à haut débit.
Cet article appartient à la catégorie Précolonnes HPLC, dans Colonnes HPLC et accessoires.

Questions about Colonnes de garde UHPLC NUCLEODUR®, Phényl-Hexyl, 1,8µm, 4x2mm, 3 unité(s)
What is this article?
Colonnes de garde UHPLC NUCLEODUR®, Phényl-Hexyl, 1,8µm, 4x2mm, 3 unité(s) 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.
Which category should I open next?
The category is HPLC columns & accessories. The sub-category is HPLC guard columns. The catalogue is Chromatographie.
