Beschreibung: Platten zur Festphasenextraktion (SPE), 96-round well plate, Bond Elut™, Polymere Sorbenzien, Plexa, 30 mg

Lieferant: VARIAN

Beschreibung: The PLRP-S family of products consists of a range of pore sizes and particle sizes, all with identical chemistry and fundamental adsorptive characteristics. The particles are inherently hydrophobic so there is no bonded phase, alkyl ligand required for reversed-phase separations. This gives a highly reproducible material that is free from silanols and heavy metal ions. Within the extensive product range are columns suitable for analytical separations and preparative purifications.

Beschreibung: Bond Elut™ Plexa PCX uses a polymeric cation exchange resin that combines the outstanding properties of Bond Elut™ Plexa - superior flow characteristics and improved analytical performance - with strong cation exchange functionalities. This mixed-mode SPE sorbent removes neutral and acidic interferences from the matrix, concentrates basic analytes and therefore improves sensitivity in the determination of basic compounds.

Beschreibung: Though highly stabilised, it is impossible to guarantee that no particles will dislodge from the column wall. When used in valve-switching applications, the use of a particle trap can prevent scarring of the rotors.

Beschreibung: Bond Elut™ SCX ist ein starker Kationenaustauscher mit einem sehr niedrigen pKa. Obwohl der pKa dem von Bond Elut™ PRS ähnelt, erhöht das Vorhandensein des Benzolrings in der Funktionsgruppe das Potenzial für unpolare Wechselwirkungen. Diese unpolare Eigenschaft wird besonders wichtig, wenn Ionenaustausch aus wässrigen Systemen durchgeführt wird, wo Selektivität gegenüber Verbindungen mit kationischem und unpolarem Charakter beobachtet wird.

Beschreibung: Bond Elut™ DEA bears some resemblance to Bond Elut™ NH₂ in its properties but with a slightly lower capacity as an anion exchange sorbent. DEA has a moderately non-polar character due to the alkyl side chains on the amino functionality. These groups still afford a medium level of polarity, higher than C₈ but less polar than C₂ or CN-E.
