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.

B&M® Diol is a silica gel based tip SPE with silica gel-like release properties. It extracts polar samples from non-polar solutions through polar interaction, is similar to unbound silica gel in the nature of hydrogen bond interaction with the sample, and can differentiate structurally similar compounds such as structural isomers, as well as silica gel minicolumns. It can also be used to isolate nonpolar compounds because the carbon chains in the bound phase provide sufficient nonpolar force to hold hydrophobic samples, with solvent ratio selectivity different from silica gel.  Diol is commonly used to isolate drugs or metabolites, such as THC, from biological solutions, such as urine samples. It is equivalent to Agilent Bond Elut 2OH and Waters Sep-Pak Diol.

B&M® CN is a silica gel-based cyanopropyl filler that can be used as a non-polar adsorbent to extract polar and non-polar molecules from aqueous solutions, as well as polar molecules from relatively non-polar solvents. In addition, cyanopropyl acts as a complex ligand to enrich some metal ions in aqueous solution.
Cyanopropyl is a weakly hydrophobic filler of the silica matrix and can be used as a direct or reverse phase adsorbent. Under the conditions of the reversed phase, nonpolar or slightly polar acidic, neutral and basic compounds are extracted from aqueous solutions. Under direct phase conditions, polar compounds are extracted from nonpolar organic solutions. In addition, cyanopropyl acts as a complex ligand to enrich some metal ions in aqueous solution. For strong hydrophobic substances that bind irreversibly at the stationary C18 phases, the stationary CN phases are a more suitable choice.   Equivalent to Waters Sep-Pak CN.

B&M® C8 is a moderately hydrophobic reversed-phase silica matrix filler that is similar in adsorption to the C18 bond and holds nonpolar compounds together mainly due to the hydrophobic interactions of nonpolar carbon bonds.

Because the carbon bond of C8 is shorter than that of C18, the retention of nonpolar compounds is weaker than that of C18, which helps to elut samples with excess adsorption of nonpolar compounds.

If the use of C18 makes it difficult to eludate nonpolar objects, C8 can be used instead.

B&M® Silica is a polar extraction column with unbound silica gel as an adsorbent. It is slightly acidic and has a strong polarity. It is used to separate non-polar, slightly polar compounds, oils, fats, etc., especially substances with a similar structure. 

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

B&M®  SCX - это сильная катионообменная экстракционная колонка на основе силикагеля, связанного с функциональными группами фенилсульфокислоты. Она используется для экстракции органических оснований или обессоливания биомолекул.

Часто смешивается с C18 для экстракции органических оснований, таких как органические основания, антимикробные препараты, лекарства, аминокислоты, катехолы, гербициды, поверхностно-активные вещества и так далее.

B&M® SAX is a strong anion exchange extraction column based on silica gel bound to quaternary ammonium functional groups. It is mainly used to extract 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.

B&M® PRS is a silica gel-based strong cation exchange extraction column, PRS is bonded by a functional group of propyl sulfonic acid, slightly less acidic than SCX, with a unique selection of new for the extraction of weak cations such as pyridine, etc., with high recovery, widely used in the pre-treatment of malachite green samples.

Equivalent to Agilent Bond Elut PRS.

B&M® PSA is a silica gel-based ethylenediamine-N-propyl extraction column, PSA contains two amines whose pKa is 10.1 and 10.9, respectively. Its selectivity is similar to amines, and it can be used as a normal or reversed-phase column, with a stronger polarity than C18 and a weaker polarity than silica gel, and it has good selectivity for different compounds of medium polarity or a wider polarity range in different systems.

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