Description
CHROMABOND QuEChERS Mix I (6,5 g) Alu is a citrate extraction salt mix for QuEChERS workflows in food and environmental residue analysis. Each stick contains 4000 mg MgSO4, 1000 mg NaCl, 500 mg Na2H-citrate · 1,5 H2O and 1000 mg Na3-citrate · 2 H2O, individually pre-weighed to deliver a reliable 6,5 g extraction portion. The salts are packed in aluminium pouches for convenient single-use dosing during the buffered QuEChERS extraction step. A pack of 50 sticks supports efficient sample preparation without repeated bulk weighing of hygroscopic salts. This aluminium-pouch format from manufacturer Macherey-Nagel suits laboratories that prefer flexible addition of extraction salts into their own centrifuge tubes. Pre-portioned sticks help standardise salt ratios, reduce handling time and support reproducible multi-residue methods for pesticides and related analytes across routine analytical series.

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 & 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.
