Benzo(a)pyrene (BaP), also known as 3,4-benzo(a)pyrene, is a common highly reactive indirect carcinogen and is one of the three most potent carcinogens recognized in the world. According to the requirements of the Chinese national standard GB2716-2005 "Hygienic Standard for Edible Vegetable Oils", the safety limit of BaP in edible vegetable oil products is no more than 10 μg/kg.
B&M® BaP has excellent recoverability and reproducibility to meet the determination needs of benzo(a)pyrene in animal and vegetable oils and fats, to ensure accurate and consistent results, and to significantly improve operational efficiency.

Alumina is a typical Lewis acid that does not have two electrons in the center of the aluminum atom, it is a strong polar adsorbent similar to silica gel; It is available in three high activity levels: acidic, basic, and neutral; alumina also has a special effect on the π-electrons of aromatic hydrocarbons; and it is more stable than silica gel under high pH conditions. The main confinement mechanisms are the Lewis acid-base interaction, the polar interaction, and ion exchange.
B&M® Alumina-N (pH=7.5) is also a strongly polar adsorbent. At high pH, alumina is more stable than silica gel with unbound functional groups. Smaller particles provide high extraction efficiency, which is why small columns (50 mg) are most often used. This adsorbent has an electrically neutral surface and promotes the retention of electron-rich compounds such as aromatics and aliphatic amines. It is also capable of holding compounds containing electronegative groups (e.g., functional groups containing atoms such as oxygen, phosphorus, and sulfur). Alumina-N can be used for the extraction and separation of polar and non-polar substances in water-soluble and non-water-soluble samples, respectively.

The surface of B&M® Alumina-B (pH = 10) is oriented to retain positively charged or hydrogen-bonded substances. Alumina pre-treated with alkaline solutions has anionic properties and is cation exchange. In addition, it retains electron-donor samples such as neutral amines, although the surface also has the properties of a Lewis base. This ability is much lower for neutral and acidic alumina. In addition, strong hydrogen bonding is possible on alumina-B, making it useful for polar cationic samples.

The acidic properties of Lewis B&M® Alumina-A (pH = 4.5) are enhanced, and the adsorbent is better able to retain electron-rich compounds. In addition, the weak cationic nature of the adsorbent allows it to more easily hold neutral and negatively charged substances (e.g., electrically neutral acids or acidic anions) on the surface when pretreated with an acidic solution, while positively charged substances are not retained as well. The weak ion exchange property also increases the probability of retention of negatively charged substances.

B&M® WCX is a hybrid column for solid-phase extraction with weak cation exchange and hydrophobicity, containing slightly 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 from 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-wet" 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.

The B&M® C8/SCX is a silica gel-based packing column with C8 and strong cation exchange SCX (C8/SCX) mixed in an optimal ratio to provide a dual containment mechanism in which the C8 functional group interacts with the hydrophobic analyte groups and the SCX functional group interacts with the protonated amino group. Due to such strong interactions, stronger wash conditions can be used to remove co-extracts that may interfere with UV detection or cause ion suppression in LC-MS. The steady-state phase is not capped, allowing for additional interactions between the residual silanol groups and the polar analytes, thereby contributing to improved retention.
Most suitable for purification of basic (cationic) or neutral compounds such as drugs and metabolites from aqueous solutions, urine and blood.
