Description
Chromabond QuEChERS Mix II (5 g) is an acetate extraction mix supplied ready-dispensed in 50 mL centrifuge tubes for streamlined sample preparation in residue analysis. Each tube contains 4000 mg magnesium sulfate and 1000 mg sodium acetate, individually pre-weighed to support reproducible QuEChERS workflows for food, agricultural, and environmental matrices. The polypropylene centrifuge tubes are closed with polyethylene lids, helping maintain salt integrity until use and simplifying handling at the bench. Packaged as 50 pieces, this format suits routine multi-residue screening where consistent salt ratios and reduced weighing steps improve throughput. The acetate-buffered extraction approach is widely applied when polar and moderately polar analytes must be recovered efficiently prior to clean-up and chromatographic determination. Offered from manufacturer Macherey-Nagel, the mix integrates into established QuEChERS protocols without additional bulk salt preparation. Laboratories benefit from defined fill weights, single-use tube convenience, and clear pack sizing for inventory planning in high-volume analytical environments.

Questions about Chromab. QuEChERS Mix II (5 g), 50 mL
What is this article?
Chromab. QuEChERS Mix II (5 g), 50 mL 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.
What should I check before I order?
