Beschrijving
CHROMABOND QuEChERS Mix I (6.5 g) Alu is een citrate-extractiezoutmengsel voor QuEChERS-workflows bij residuanalyse van voeding en milieu. Elke stick bevat 4000 mg MgSO4, 1000 mg NaCl, 500 mg Na2H-citrate · 1.5 H2O en 1000 mg Na3-citrate · 2 H2O, afzonderlijk vooraf afgewogen om een betrouwbare extractieportie van 6.5 g te leveren. De zouten zijn verpakt in aluminiumzakjes voor handige eenmalige dosering tijdens de gebufferde QuEChERS-extractiestap. Een verpakking van 50 sticks ondersteunt efficiënte monstervoorbereiding zonder herhaald afwegen van hygroscopische zouten in bulk. Dit aluminiumzakjesformaat van fabrikant Macherey-Nagel past bij laboratoria die de voorkeur geven aan flexibele toevoeging van extractiezouten in hun eigen centrifugebuizen. Vooraf geportioneerde sticks helpen zoutverhoudingen te standaardiseren, verkorten de verwerkingstijd en ondersteunen reproduceerbare multiresidumethoden voor pesticiden en verwante analyten in routinematige analytische series.
Dit artikel maakt deel uit van SPE-cartridges & kolommen, in SPE & monstervoorbereiding.

Questions about Chromab. QuEChERS Mix I (6.5 g), Alu
What is this article?
Chromab. QuEChERS Mix I (6.5 g), Alu 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.
