Description
Chromafix C18 ec (S) solid phase extraction cartridges are SPE devices for sample preparation, clean-up and enrichment in chromatographic workflows. They employ an endcapped C18 reversed-phase sorbent with a minimum fill quantity of 90 mg, aimed at retention of non-polar to moderately polar analytes while limiting residual silanol activity through endcapping. The small (S) format suits lower sample volumes, reduced solvent use and compact SPE setups on manifolds or automated systems. Supplied in packs of 50 pieces, these cartridges function as chromatography accessories for extraction, concentration and purification steps before HPLC, GC or related analytical methods. CHROMAFIX C18 ec (S) units from manufacturer Macherey-Nagel are selected when endcapped C18 chemistry and a defined minimum bed mass of 90 mg are required. Net pack weight is 0,20 kg. Laboratories use this phase for hydrophobic-interaction SPE where controlled secondary interactions and a compact sorbent bed support efficient method transfer and routine clean-up.

Questions about Chromafix C18 ec (S)
What is this article?
Chromafix C18 ec (S) 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.
