Sample pretreatment

During ion chromatographic analysis, impurities are often present in the sample. 
For example, organic substances contaminate the packaging of an ion-chromatographic column, reduce the separation ability of the column
and column life, and impurity ions will interfere with the separation of target ions.

BM Life Sciences' B&M® IC Series ion chromatography sample pretreatment columns are designed based on the solid state principle.

B&M® WCX is a hybrid Tip SPE with weak cation exchange and hydrophobic action, containing weakly acidic functional groups of carboxylic acids. It is used to pre-process samples of highly basic compounds such as quaternary ammonium. It is a weak cation exchange, hybrid, water-wetted polymer adsorbent that is stable in the pH range of 0 to 14.
WCX has all the benefits of HLB. A stable, highly selective solid-phase extraction method using WCX allows monitoring, validation and quantification of highly basic compounds such as quaternary ammonium in a variety of sample matrices.

Equivalent to Waters Oasis WCX.

B&M® WAX is a reversed-phase and anion exchange composite "water-wet" polymer adsorbent with anion exchange and reverse-phase adsorption modes and good water wettability. The matrix is pure, stable in the pH range 0-14, stable in organic solvents, with a high specific surface area, high exchange capacity and adsorption of all types of polar and non-polar compounds.

It is the equivalent of Waters Oasis WAX.

B&M® MCX is a reversed-phase and cation-exchange composite "water-wetted" polymer adsorbent with cation exchange and reversed-phase adsorption modes and good water wettability. The matrix is pure, stable in the pH range of 0-14, stable in organic solvents, has a high specific surface area, high exchange capacity, high selectivity and sensitivity to basic compounds, and is especially suitable for the detection of melamine in milk, food and feed.

It is equivalent to Waters' Oasis MCX and Varian's Plexa PCX.

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.

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.

B&M® Silica is a polar Tip SPE with unbound silica as an adsorbent, slightly acidic and highly polar. It is used to separate non-polar and slightly polar compounds, oils and fats, especially similar in structure.                                                                                                              
Equivalent to Agilent Bond Elut Silica and Waters Sep-Pak Silica.

B&M® SCX is a highly cationized silica gel-based Tip SPE with phenylsulfonic acid functional groups. It is used for the extraction of organic bases or the desalination of biomolecules.
Often mixed with C18 to extract organic bases such as organic bases, antimicrobials, pharmaceuticals, amino acids, catechols, herbicides, surfactants, etc.

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

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.
