Hydrofobe fase met alternatieve selectiviteit vergeleken met klassieke C18-modificaties. Het scheidingsprincipe is gebaseerd op twee retentiemechanismen - π-π-interacties en hydrofobe interacties. Dit zorgt voor een betere retentie van aromatische en onverzadigde stoffen. Deze stationaire HPLC-fase is gebaseerd op core-shell-technologie silicagel-deeltjes en vertoont uitstekende prestaties onder sterk waterige omstandigheden. De speciale fasemodificatie van NUCLEOSHELL® Biphenyl met iso-butyl-zijketens leidt tot een lage bleeding (bloeden) zelfs bij zeer zure pH-waarden in vergelijking met kolommen van concurrenten. Dankzij deze iso-butyl-zijketens en multi-endcapping-procedures treedt er geen fase-instorting op en is de stabiliteit in 100 % waterige mobiele fase gewaarborgd.

Questions about HPLC-kolom NUCLEOSHELL®, Bifenyl, 2,7µm, 50x4mm, 1 eenheid/eenheden
What is this article?
HPLC-kolom NUCLEOSHELL®, Bifenyl, 2,7µm, 50x4mm, 1 eenheid/eenheden is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC columns, inside HPLC columns & accessories, in Chromatografie.
An HPLC column is specified by the stationary phase, the particle size, the length and the internal diameter. A C18, 5 µm, 150 × 4.6 mm column is a different article from a C18, 3 µm, 100 × 2.1 mm column. The smaller bore belongs on a lower flow. A column has a direction and a pH range.
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 columns. The catalogue is Chromatografie.
Shelves beside this one are HPLC fittings, tubing & inline filters, HPLC guard columns and HPLC accessories.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
