CHROMABOND® SB | Volume ml: 1, Capacity mg: 100
CHROMABOND® SB | Volume ml: 1, Capacity mg: 100
Merk: Macherey-Nagel GmbH & Co. KGBeschikbaar in 6 variantenQuaternary ammonium modified silica anion exchanger for SPE (SAX)Base material silica, pore size 60 Å, particle size 45 µm, specific surface 500 m²/g, pH stability 2 to 8. Silica modified with quaternary amine. Strongly basic anion exchanger (capacity ~ 0.3 meq/g). Not suited for very strong anions such as sulphonic acids, because these are difficult to elute.Recommended application: organic acids, caffeine, saccharin.

CHROMABOND® SiOH | Volume ml: 45, Capacity mg: 5000
CHROMABOND® SiOH | Volume ml: 45, Capacity mg: 5000
Merk: Macherey-Nagel GmbH & Co. KGBeschikbaar in 13 variantenUnmodified silica phase for SPEUnmodified, weakly acidic silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8, very polar, adsorbs humidity from air, for this reason it should be kept well closed and if necessary dried before use due to its high affinity for polar compounds it should not be conditioned with polar (e.g. methanol) or water-containing solvents.Recommended applications: aflatoxins, chloramphenicol, pesticides, steroids, vitamins.
