Carboxen Adsorbent, matrix Carboxen 1006, 2 mum, bottle of 20 g

Non disponible en dehors du Royaume-Uni et de l'Irlande

Application

Carboxen^® 1006 was used as an extraction device for the determination of ochratoxins A and B in nuts and grain samples using an automated in-tube solid-phase microextraction (SPME) coupled with liquid chromatography-mass spectrometry (LC-MS).

General description

A carbon molecular sieve (CMS) is the porous carbon skeletal framework that remains after pyrolysis of a polymeric precursor. These particles are: Spherical (better packed bed performance than granular particles) Hard and non-friable (pack well, will not break) Highly porous (high surface areas) Used for molecules with an analyte size relative to C2-C5 n-alkanes Hydrophobic (can be used in high humidity environments)Generally, CMS adsorbents offer greater relative adsorptive strength compared to spherical graphitized polymer carbon (SGPC) and graphitized carbon black (GCB) adsorbents. Our Carboxen products are a type of CMS adsorbent. Have tapered pores, resulting in excellent thermodynamic properties for both adsorption and desorption (have the best thermodynamic performance of any adsorbents) The surface chemistry can be tailored for specific target analytesFor more information about any of our specialty carbon adsorbents, please visit sigma-aldrich.com/carbon

Carboxen^® adsorbent is ideally used for solid-phase microextraction (SPME). It is highly efficient in extraction of small polar molecules from aqueous solution.
