CHẤT NHỒI SCX SCX SORBENT SORBENT    SCX combines octyl and sulfonic acid functional groups in a proportional manner, offering dual retention mechanisms: octyl provides moderate hydrophobic interaction, and sulfonic acid provides strong cation exchange. For samples where C18 and C8 cause excessive adsorption and SCX retains too strongly, making elution difficult, the C8/SCX mixed-mode extraction column is an ideal solution.

CHẤT NHỒI CN SORBENT CN CN SPE cartridge is cyanopropyl extraction columns based on silica gel. With medium polarity, it can be used for reverse or normal phase extraction. It can extract non-polar acid during the reversed-phase, and extract polar compounds from the non-polar solvent during the normal phase. Usually, CN SPE Cartridge is a weakly retentive, non-polar sorbent used to extract non-polar analytes from aqueous samples

CHẤT NHỒI SAX SAX SORBENT SAX (Strong Anion Exchange) Solid Phase extraction based on a strong anion exchange polymeric phase. It is particularly suited for the extraction of weak acids (pKa 2 – 8).

CHẤT NHỒI MAX MAX SORBENT MAX SPE cartridge is a sorbent that is a kind of hybrid separation for strong anion exchange and has a kind of hydrophobic effect. MAX is mainly used for the separation and purification of quaternary ammonium salt groups of neutral medium and acidic compounds in alkaline, the pH range is between 1-14, widely used for the purification of serum and urine and as a matrix of acid and neutral of plastics products and food industry

CHẤT NHỒI FLORISIL FLORISIL SORBENT   Pesticide grade Florisil, activated at 675°C, is a highly polar, high-activity porous adsorbent capable of adsorbing low to moderately polar target compounds, such as those containing fluorine, nitrogen, and weak organic pesticides. Florisil columns are effective and cost-efficient for multi-residue pesticide detection. They are adopted by the US EPA 608 method and the Chinese Ministry of Agriculture NY/T 761 method.

MCX SORBENT MCX is a hybrid strong cation exchange solid phase extraction column based on monodisperse polymer microspheres. MCX SPE cartridge is designed to overcome the limitations of traditional silica-based mixed solid phase extraction adsorbents. Polymeric MCX sorbent has a larger surface area compared with other sorbents, so it has a high ion exchange capacity that can keep alkaline material effectively, at this time the acid resistance is strong, so it has a stable pH range of about 0-14. MCX cartridge provides dual retention modes: ion exchange and reverses phase, and the retention occurs in a clean, stable, high surface area, on stable organic copolymers in the pH 0-14 range. Polymeric MCX SPE cartridges are often used for the detection of melamine in milk and food and feed.

CHẤT NHỒI WAX WAX SORBENT

CHẤT NHỒI HLB HLB SORBENT The HLB hydrophilic lipophilic balance filler is prepared by special copolymerization technology, containing a specific proportion of hydrophilic and hydrophobic groups: hydrophobic divinylbenzene structure retains non-polar compounds, hydrophilic N-vinyl The pyrrolidone structure retains polar compounds. The filler has good water wettability, and the hydrophilic-lipophilic balance can be adjusted by the water phase, so as to obtain the desired selectivity. HLB has a good recovery rate for non-polar to medium-polar acidic, neutral, and basic compounds, and is especially suitable for the treatment of complex matrices such as blood, urine, and food
