Questions about SPE-PP-kolommen CHROMABOND® HR-XAW, 3 ml volume, adsorbensgewicht 500 mg, 30 stuks
What is this article?
SPE-PP-kolommen CHROMABOND® HR-XAW, 3 ml volume, adsorbensgewicht 500 mg, 30 stuks is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in SPE-cartridges & kolommen, inside SPE & monstervoorbereiding, in Chromatografie.
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 & monstervoorbereiding. The sub-category is SPE-cartridges & kolommen. The catalogue is Chromatografie.
Shelves beside this one are Sorbentia, silicagel & ionenwisselaars and Flash-, lege & glazen chromatografiekolommen.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
