Polymeric MAX, MCX, and HLB SPE Cartridges

Polymeric MAX SPE cartridges

Polymeric MAX SPE cartridges are used for the extraction of acidic compounds. MAX is a mixed strong anion exchange adsorbent obtained by bonding quaternary ammonium to a highly crosslinked PS/DVB surface. It has strong anion exchange and reverse phase retention, and is suitable for the extraction of acidic compounds.

Polymeric MAX SPE cartridges can be wetted and are not easy to penetrate, whose pH tolerance range is wide. They are stable acid compound extraction cartridges in the organic solvent.

Polymeric MCX SPE cartridges

Polymeric MCX SPE cartridges are used to overcome the limitations of traditional silica matrix mixed solid-phase extraction adsorbent. It is a mixed type of strong cation exchange, water-wettable polymer adsorbent, and has high selectivity and sensitivity to basic compounds. Polymeric MCX SPE cartridges provide dual retention modes: ion exchange and inversion, and retention occurs on a clean, stable, high-surface area, a stable organic copolymer with a pH range of 0 to 14.

Polymeric MCX SPE cartridges require a high adsorption capacity to effectively extract alkaline compounds from biological substrates using a mixed solid-phase extraction absorbent. The curved-type silica matrix mixed adsorbent of polymeric MCX SPE cartridges is synthesized through a complex process that is difficult to control and has a relatively low exchange capacity (within the range of 0.06-0.2meqlg).

Polymeric HLB SPE cartridges

Polymeric HLB SPE cartridges are used to extract nonpolar to medium-polarity acidic, neutral, and alkaline compounds. HLB hydrophilic and lipophilic equilibrium packing is prepared by special copolymerization technology and contains a specific proportion of hydrophilic and hydrophobic groups.

Polymeric HLB SPE cartridges can recycle nonpolar to the medium polarity of acidic, neutral, and alkaline compounds and are especially suitable for complex matrices, such as blood, urine, and food processing.
