SelectCore Silica

50 μm

Spherical bare silica as the normal phase adsorbent with weak acidity and strong polarity.

SelectCore C18

50 μm

Octadecyl silane bonded high purity, spherical silica particles with high carbon loading, strong hydrophobicity and good chemical stability.

SelectCore NH2

50 μm

Ammonia-propyl modified high purity, spherical silica particles with both polar and weak anion exchange properties, providing weak anion exchange and hydrophilic interactions.

SelectCore PSA

50 μm

Ethylenediamine-N-propyl bonded high purity, spherical silica particles which contain both primary and secondary amines, used for the extraction of strongly acidic compounds from aqueous samples based on a weak anion exchange retention mechanism.

SelectCore SCX

50 μm

Propyl sulfonic acid bonded high purity, spherical silica particles with strong cation exchange capability, which is recommended for extraction of basic compounds.

SelectCore SAX

50 μm

Quaternary ammonium bonded high purity, spherical silica particles, which have a strong anion exchange capacity for extracting weakly acidic compounds such as carboxylic acids.
