La famille de produits PLRP-S se compose de plusieurs tailles de pores et de particules ayant tous la même structure chimique et les mêmes caractéristiques d'adsorption fondamentales. Les particules sont intrinsèquement hydrophobes, si bien qu'aucun ligand alkyle de phase greffée n'est nécessaire pour des séparations en phase inverse. Cela donne un matériau hautement reproductible exempt de silanols acides et d'ions de métaux lourds. La large gamme de produits disponibles propose des colonnes adaptées aux séparations analytiques et aux purifications préparatives.

Des gaz propres permettent de réduire le risque d'endommagement de la colonne et d'améliorer la précision ainsi que la sensibilité. Ces filtres incassables et avec indicateur offrent une sensibilité élevée à l'oxygène et à l'humidité. Ils peuvent être installés en quelques secondes sans le moindre outil.

Bond Elut AccuCAT cartridges are mixed bed SPE cartridges consisting of a strong cation exchange (SCX) and a strong anion exchange (SAX) sorbent packed into one bed. AccuCAT is effective for the extraction of acidic, basic and neutral analytes from urine and other biological samples. AccuCAT is particularly effective for catecholamine extraction from bio fluids.

Supplier: VARIAN

Chem Elut sorbent for rapid, general sample preparation of biological samples such as plasma, serum, whole blood and urine. Chem Elut products are available in buffered and unbuffered formats. The buffered devices can be used for simple scrubbing operations on organic reactions. The base-treated cartridge can remove residual acid compounds from a variety of matrices.

Bond Elut™ PSA is an alkylated amine sorbent that contains two different amino functionalities, one secondary and one primary. This gives a slightly higher pKa and ionic capacity compared to Bond Elut™ NH₂. The PSA functional group is a very effective bidentate ligand and is therefore an excellent sorbent for chelation applications. PSA has a significantly higher carbon load than most amino functional sorbents and thus is a better choice for polar compounds, which retain too strongly on Bond Elut™ NH₂.

CBA is a mid-polarity sorbent and weak cation exchanger (pKa 4,8). It can be used with a wider range of counter-ions than lower pKa sorbents like SCX and will demonstrate easier elution of quaternary amine functionalised analytes.

Les colonnes HPLC Hi-Plex offrent une meilleure efficacité, réduisent les pressions de fonctionnement et rallongent la durée de vie des colonnes à partir de matériaux monodispersés. Avec une plage de contre-ions de ligands offrant une sélectivité et une résolution optimales, et des matériaux correspondant aux définitions de l'USP des types de milieux L17, L19, L34 et L58, la gamme Hi-Plex est idéale pour les séparations isocratiques utilisant comme éluant de l'eau ou de l'acide dilué. Cela simplifie votre configuration système HPLC et élimine l'utilisation de solvants organiques potentiellement dangereux.

Microsorb™ Cyano, a cyanopropylsilane-covered silica, is unique in that it spans both the normal and reversed phase separation modes. When used with aqueous organic mobile phases, compounds elute in an order typical of reversed phase, with polar compounds eluting quickly and hydrophobic compounds being more retained.
