Solid phase extraction column

Cleanert Plus SPE adopts particle size optimized fillers, new sieve plate materials and designs, and a unique pre activation process, which have excellent characteristics of fast, simple, and reliable use. It can save 1/3 of the workload and avoid the common problem of column blockage caused by viscous samples. Make sample pretreatment simpler, faster, more worry free, and more reassuring- Stable column flow rate and anti clogging: spherical packing or amorphous packing with uniform particle size distribution is used to ensure the uniformity of flow rate. At the same time, the new sieve plate material design ensures the flow rate of viscous samples, avoiding column clogging caused by viscous/dirty samples- Reverse phase column activation free: adopting new surface treatment technology for fillers and product pre activation process; Eliminating the activation step during the use of reverse phase columns can save 1/3 of the labor

Filler for silicone matrix

C18 (capped), C18 (unsealed), C8，CN,NH2,PSA,SAX,COOH,PRS,SCX,Silica,Diol， All use high-quality, high-purity silicone gel, and undergo unique surface treatment by Aijer Technology before bonding, which greatly reduces the surface activity of the silicone gel and minimizes the non adsorption and de tail of polar compounds, ensuring the recovery and reproducibility of the sample. Average pore size: 60 Å, pore volume: 0.8 cm2/g, specific surface area: 480 m2/g.

Adsorption type packing material

Florisil (magnesium silicate), PestiCarb (graphitized carbon black), alumina (Alumina-N, neutral); Alumina-A， acidic; Alumina-B， Alkaline). The purification of adsorption is mainly achieved through surface adsorption. Cleanert adsorption fillers undergo strict activation treatment and have excellent characteristics of high purification effect, high recovery rate, and high reproducibility. They have been widely used in the pretreatment of organic matter in food. Typical applications include sample pretreatment of well-known Sudan Red and Peacock Green.

Mixed packing, dedicated column, method package

Cleanert C8/SCX; PestiCarb/NH2； Cleanert SUL-5 (sulfonamide specific column); DNPH Silica gas sample collection tube; Pre treatment package for 51 pesticide residues in vegetables and fruits; Textile - Pre treatment method package for banning azo dyes

SLE diatomaceous earth

The azo dye specific column developed by Bona Aijer Technology uses diatomaceous earth treated with a special process, which has the highest specific surface area and the lowest surface activity, providing an ideal support surface for liquid-liquid distribution and maximizing the recovery rate of aromatic amines. In addition, the unique column tube design ensures a stable column bed and excellent flow velocity. Diatomaceous earth undergoes special deactivation treatment to ensure sample recovery rate. Average particle size: 150 mesh; Average particle size: 50 μ m.

MAS

MAS (Multi function Impurity Adsorption SPE) has extended dispersed solid-phase extraction to the analysis of veterinary drug residues, food additives, and drug metabolism using the "multi mechanism impurity adsorption extraction purification method". This method mainly uses multifunctional composite adsorbent materials to adsorb the main interfering impurities in biological samples; At the same time, the strongly water-soluble test substance is left in the sample solution to achieve purification and enrichment.

Cleanert IC ion chromatography pretreatment column

The Cleanert IC series ion chromatography sample pretreatment column is developed based on the principle of solid phase extraction, using high-purity materials and utilizing the mechanism of reverse phase adsorption and ion exchange to effectively remove impurities such as organic matter and impurity ions from the sample, avoiding contamination of the ion chromatography column by impurities and their impact on separation.
