Polymeric MAX, MCX, And HLB SPE Cartridges

Polymeric MAX SPE cartridges are used to the extraction of acidic compounds. MAX is a mixed strong anion exchange adsorbent obtained by bonding quaternary ammonium to 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 wetting 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 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 occur 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 are used to extract nonpolar to the medium polarity of acidic, neutral and alkaline compounds. HLB hydrophilic and lipophilic equilibrium packing is prepared by special copolymerization technology and contain 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.

Advantages of polymeric MAX SPE cartridges
1. Easy operation, good reproducibility;
2. Save the cost of instruments and consumables;
3. No blank background interference;
4. High recovery rate;
5. High specific surface area and large exchange capacity;
6. Stable quality.

Advantages of polymeric HLB SPE cartridges
1. Universal packing, wide application range;
2. High water infiltration, not afraid of solvent drainage, not easy to penetrate;
3. High recovery and good reproducibility;
4. Tolerable to PH 1 – 14, compatible with most solvents;
5. Adsorption capacity and sample load were much higher than C18 bonded silica gel.
