Beschrijving
CHROMABOND QuEChERS Mix XLVII is een gebruiksklaar Diamino/Carbon/C18 ec-clean-upmengsel, bereid volgens AOAC voor dispersieve vastefase-extractie in residuanalyse. Elke portie bevat 1200 mg magnesium sulfate (MgSO4), 400 mg CHROMABOND Diamino, 400 mg CHROMABOND Carbon en 400 mg CHROMABOND C18 ec, overeenkomend met een totaal vulgewicht van 2.4 g. De sorbentia zijn afzonderlijk vooraf afgewogen in centrifugebuizen van 15 mL polypropyleen, afgesloten met deksels van polyethyleen, zodat laboratoria rechtstreeks van extractoverdracht naar clean-up kunnen gaan zonder extra weegstappen. Deze combinatie ondersteunt de verwijdering van polaire matrixcomponenten, pigmenten en niet-polaire interferenties uit voedings- en milieumonsterextracten vóór chromatografische bepaling. Aangeboden als een verpakking van 50 buizen van fabrikant Macherey-Nagel, verbetert het formaat de consistentie van batch tot batch en verkort routinematige QuEChERS-workflows. Vooraf gedoseerde clean-upmengsels helpen analytische laboratoria multiresidu-monstervoorbereiding te standaardiseren en tegelijk de hanteringstijd en het risico op weegfouten aan de werkbank te verminderen.
Dit artikel maakt deel uit van SPE-cartridges & kolommen, in SPE & monstervoorbereiding.

Questions about Chromab. QuEChERS Mix XLVII (2.4 g)
What is this article?
Chromab. QuEChERS Mix XLVII (2.4 g) is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in SPE-cartridges & kolommen, inside SPE & monstervoorbereiding, in Chromatografie.
An SPE cartridge holds a bed of sorbent. Bed mass, sorbent chemistry and volume are the specification. A 100 mg C18 cartridge and a 1 g C18 cartridge take different sample loads and different elution volumes. The method names all three.
Solid-phase extraction holds a compound on a sorbent while the rest of the sample is washed away, then releases it in a small volume. The sorbent, the bed mass and the solvents are the method. Silica, ion exchangers and polymer phases do different jobs. A flash column is the same idea scaled toward purification rather than trace cleanup. The molecules are on PubChem, named by IUPAC.
Which category should I open next?
The category is SPE & monstervoorbereiding. The sub-category is SPE-cartridges & kolommen. The catalogue is Chromatografie.
Shelves beside this one are Sorbentia, silicagel & ionenwisselaars and Flash-, lege & glazen chromatografiekolommen.
