Description
CHROMABOND QuEChERS Mix XII (5 g) is a ready-to-use extraction salt mixture for QuEChERS sample preparation in residue analysis. Each portion contains 4000 mg magnesium sulfate (MgSO4) and 1000 mg sodium chloride (NaCl), pre-weighed to a total of 5 g for reproducible extraction workflows. The salts are supplied individually dispensed in 15 mL polypropylene centrifuge tubes with polyethylene lids, so sample and solvent can be added directly without separate weighing steps. This format supports efficient phase separation and the salting-out step used in multi-residue methods for pesticides and related contaminants in food and environmental matrices. The extraction mix from manufacturer Macherey-Nagel helps laboratories cut preparation time and reduce weighing variability in routine analytical sequences. Magnesium sulfate drives water removal while sodium chloride promotes partitioning between aqueous and organic phases. Packaged as 50 pre-filled centrifuge tubes, the product fits standardized QuEChERS protocols and high-throughput screening. Consistent tube-to-tube composition supports stable recoveries and straightforward method transfer across instruments and sites.

Questions about Chromab. QuEChERS Mix XII (5 g)
What is this article?
Chromab. QuEChERS Mix XII (5 g) is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in SPE cartridges & columns, inside SPE & sample preparation, in Chromatography equipment.
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 & sample preparation. The sub-category is SPE cartridges & columns. The catalogue is Chromatography equipment.
Shelves beside this one are Sorbents, silica gel & ion exchangers and Flash, empty & glass chromatography columns.
