Nos sels de qualité HPLC sont excellents pour une utilisation comme tampons dans les analyses HPLC, l'absorption étant testée à diverses longueurs d'onde pour tous les sels. Les solutions tampons préparées à partir de ceux-ci sont généralement utilisées en chromatographie liquide haute performance en phase inversée (RP-HPLC) lorsque l'échantillon forme des groupes acides (ions oxonium (H3O+)) ou basiques (ions hydroxyde (OH−)). Les tampons atténuent l'impact des ions oxonium et hydroxyde, réduisant ainsi les fluctuations de pH.

Questions about Hydrogénophosphate dipotassique, min. 99 %, HPLC, 50 g, plastique
What is this article?
Hydrogénophosphate dipotassique, min. 99 %, HPLC, 50 g, plastique is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC accessories, inside HPLC columns & accessories, in Chromatographie.
HPLC accessories are the unions, the ferrules, the lamp and the mixer parts around the pump and the detector. A ferrule that has been swaged on one fitting does not reseal on another. The part has to be the one for that thread and that tubing.
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 accessories. The catalogue is Chromatographie.
Shelves beside this one are HPLC columns, HPLC fittings, tubing & inline filters and HPLC guard columns.
