Colonne cromatografiche

Supplier: Merck

Ascentis® Express high-speed, high-performance liquid chromatography columns are based on the wider-pore 160 Å Fused-Core® particle design to provide adequate spacing for the long-chain C30 ligands.

Supplier: Merck

These LpDNPH cartridges are suitable for sampling carbonyls in ambient, indoor, and industrial atmospheres. The derivatives are eluted from the cartridge in acetonitrile and are analysed by HPLC.

Supplier: Merck

Porous Graphitic Carbon (PGC) particle packed column for separating poorly retained, polar compounds.

Supplier: Merck

Discovery® C18 columns are designed for the separation of peptides and small proteins with exceptional peak shape for basic and acidic analytes.

Supplier: Merck

Sistema per nano-LC rapida per proteine e peptidi. I capillari Chromolith® CapRod® combinano la velocità della tecnologia con silice monolitica e la sensibilità del sistema nano-LC, offrendo così analisi LC / MS estremamente rapide e sensibili.

Supplier: Merck

Le fasi stazionarie in silice monolitica Chromolith® Prep sono costituite da silice ultrapura, che derivano le loro speciali proprietà da una struttura bimodale della silice. Questa struttura è caratteristica di una nuova tecnologia 'Sol-Gel' ed è costituita da macropori e mesopori. I mesopori, con un diametro medio di 12 nm, formano la struttura porosa fine all'interno della colonna e crea un'area superficiale molto ampia su cui si verifica l'assorbimento dei composti.

Stainless steel LiChroCART® cartridges are available with various types of Purospher® sorbents.

Supplier: Merck

Stainless steel LiChroCART® cartridges are available with LiChrospher® sorbents. Ideal for separation of compounds under basic eluents.

Supplier: Merck

Stainless steel Hibar® columns are complete with endfittings. These columns are available with various types of LiChrospher® sorbents.

Supplier: Merck

Stainless steel Hibar® columns are complete with endfittings. These columns are available with Chiradex® sorbents. Ideal for separation of enantiomers of different class of substances.

Supplier: Merck

ChiraDex® is a versatile HPLC column characterised by broad enantioselectivity and can be used for the separation of enantiomers of numerous different classes of substances. ChiraDex® is based on beta-cyclodextrin covalently linked to spherical particles of silica, and is ideal for chiral separation of hydrocarbons, steroids, phenol esters and derivatives, aromatic amines, heterocycles with five- to seven-membered ring. Simply composed RP-eluents can be used in most separations.

Supplier: Merck

These SUPELCOSIL LC-DB phases are specially deactivated for basic compounds. These columns provide less retention, better peak shape, and higher efficiency for organic bases than can be obtained on conventional reversed-phase columns.

Supplier: Merck

These non-polar methyl silicone bonded poly(dimethyl siloxane) columns are used to separate the sample components according to boiling point.

Supplier: Merck

The Discovery® HS C18 columns provide the best suitable selectivity for many applications.

Supplier: Merck

Ascentis® Express HILIC high-speed, high-performance liquid chromatography columns are based on Fused-Core® particle design. The Fused-core particle provides a thin porous shell of high-purity silica surrounding a solid silica core.

Supplier: Merck

Ascentis® Silica HPLC columns for the classic use in normal phase HPLC.
