MAX Tip SPE Pipette TipsExtraction Tips

2024-08-28

B&M® MAX is a reversed-phase and strong anion exchange complex "water-wet" polymer adsorbent. Its matrix consists of N-vinylpyrrolidone and divinylbenzene polymerized in a certain ratio (HLB), and then the quaternary ammonium group (CH2N(CH3)2C4H9+) is attached to the HLB, which provides two adsorption modes: anion exchange and reversed-phase adsorption, stable in the pH range of 0-14 and has good water wettability. It has high selectivity and sensitivity to acid compounds and can overcome the limitations of traditional hybrid adsorbents for silica gel matrix-based solid-phase extraction.

HLB Tip SPE Pipette TipsExtraction Tips

2024-08-28

B&M® HLB is a Tip SPE based on N-vinylpyrrolidone and divinylbenzene with hydrophilic and hydrophobic groups on the surface, which provides balanced adsorption of a wide range of polar and non-polar compounds and high adsorption capacity, even when the adsorbent runs out after balancing. This means that very high sensitivity can be achieved with a simple method. The matrix is clean, stable in the pH range of 0-14, stable in a wide range of organic solvents and has a high adsorption capacity (3-10 times higher than that of C18). It is mainly used for the extraction of complex biological samples (e.g., blood, plasma, acidic, neutral, or basic drugs in body fluids).

Equivalent to Waters Oasis HLB.

SAX Tip SPE Pipette TipsExtraction Tips

2024-08-28

B&M® SAX is a silica gel-based strongly anion exchange Tip SPE bound to quaternary ammonium functional groups. It is mainly used for the extraction of weak-anionic compounds such as carboxylic acids. This strong anion exchanger can be used to extract negatively charged compounds from aqueous and non-aqueous solutions and is especially suitable for the extraction of weak acids. It is usually used to remove strong anions from samples (organic acids, nucleotides, nucleic acids, sulfonates, inorganic salt ions, etc.), desalination of biomolecules, etc.

Equivalent to Supelco Supelclean LC-SAX, Agilent Bond Elut SAX, SampliQ Si-SAX.

PSA Tip SPE Pipette TipsExtraction Tips

2024-08-28

B&M® PSA is a silica gel-based tip SPE with ethylenediamine-N-propyl, PSA contains two amines with pKa 10.1 and 10.9. Its selectivity is similar to that of amines, and it can be used as a conventional or reversed-phase column, with a polarity that is stronger than that of C18 and weaker than that of silica gel, and has good selectivity for various compounds of medium polarity or a wide range of polarities over a wide range of systems.

PSA can chelate with metal ions, used to extract metal ions. It is widely used in sample pre-treatment for the analysis of pesticide residues as well as organic acids, pigments, metal ions and phenols.

NH2 Tip SPE Pipette TipsExtraction Tips

2024-08-22

B&M® NH2 (amino) is a silica gel-based aminopropyl SPE. It has a polar stationary phase and a weak anion exchanger, which can achieve retention by weak anion exchange (aqueous solutions) or polar adsorption (non-polar organic solutions), and thus has a dual role. When used in non-polar solutions (e.g., hexane) for pretreatment, it can form hydrogen bonds with molecules with functional groups -OH, -NH, or -SH, aminopropyl PKa=9.8; it is weaker than SAX with anions, and it can be used as a weak anion exchanger to remove strong anions such as sulfonate from samples in aqueous solutions with pH<7.8.


The aminopropyl bound phase has strong polar adsorption in nonpolar organic solutions and weak anion exchange retention in aqueous solutions. NH2 works well in a wide range of sample matrices and can be used in the food, environmental, pharmaceutical, and medical industries.

Equivalent to Agilent Bond Elut NH2 and Waters Sep-Pak NH2.
