Description
CHROMABOND QuEChERS Mix I (6,5 g), 50 mL is a citrate extraction salt blend pre-dispensed for QuEChERS workflows that require larger centrifuge tubes. Each unit contains 4000 mg MgSO4, 1000 mg NaCl, 500 mg Na2H-citrate · 1,5 H2O and 1000 mg Na3-citrate · 2 H2O, individually weighed into a 50 mL polypropylene centrifuge tube with a polyethylene lid. The buffered citrate composition supports controlled extraction pH and is intended for multi-residue sample preparation of food and related matrices before dispersive clean-up and instrumental analysis. Delivered as a pack of 50 pieces from manufacturer Macherey-Nagel, the 50 mL format accommodates higher sample volumes or solvent loads while keeping salt ratios fixed at 6,5 g total per tube. Laboratories benefit from reduced weighing steps, consistent batch composition and direct compatibility with standard 50 mL centrifuge rotors. This Mix I configuration streamlines the extraction stage of QuEChERS methods in high-throughput residue testing environments.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. QuEChERS Mix I (6.5 g), 50 mL
What is this article?
Chromab. QuEChERS Mix I (6.5 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?
