Chromatographic separation is an effective method for separating components in complex mixtures, which is based on different partition coefficients of different substances in stationary phase and mobile phase. When the two phases move in relative motion, these substances move together with the mobile phase and are distributed repeatedly between the two phases. Thus, different substances are eluted at different places and separation is achieved.

The performance of ion exchange resin is affected by many factors. If abnormal performance degradation of ion exchange resin occurs in daily use, we generally carry out the cause analysis and take corresponding measures according to the following sequence.

The strong base anion exchange resin contains a certain amount of moisture and should not be stored in the open air. During the storage and transportation, it should be kept moist to avoid air drying and dehydration, which will cause the resin to break. If dehydrated during the storage, the resin should be soaked in concentrated salt water (25%) and then gradually diluted. Do not put the resin into water directly in case of rapid expansion and breakage.

Sunresin has selected professional R&D and production personnel to form a technical team to adjust and optimize the resin synthesis process, and has successfully developed a new generation of high exchange-capacity styrene series macroporous strong acid cation exchange resin Seplite® LSF971 Imporve and high exchange-capacity styrene type macroporous weak base anion exchange resin Seplite® LSF973 Imporve. Special matrix white balls synthesis process design optimizes the molecular framework and pore structure. At the same time in the ascension of exchange capacity of the resin, resin strength and service life also has improved. After industrial verification, the above two resins have significantly improved the material liquid treatment c1apacity compared with the conventional Seplite® LSF971 and Seplite® LSF973 resins, and the unit consumption of water and acid-base reagents during the operation of the resin is significantly reduced. With the high praise of many manufacturers in the industry, Sunresin's new generation of high exchange-capacitySeplite® LSF971 Imporve with Seplite® LSF973 Imporve resin will bring a cost revolution to the production of biodigesters.

Strong acid ion exchange resin is a kind of granular product with sulfonic group on the crosslinked styrene skeleton. It can be used in all pH ranges (0-14), stable at various temperatures and resistant to high temperatures of 100-120℃. Therefore, it is widely used in water treatment for manufacturing pure water and soft water, as well as in pharmaceutical products, food refining, catalyst and other fields.

Sunresin has developed a series of special resins for water treatment that exceed the standard. It can specifically and accurately remove the excessive boron, fluorine, nitrate and chlorate in the water source, so as to achieve the continuous compliance with water quality standards.

Seplite® CT104 etherification system deacidification agent has the performance advantages of strong contamination resistance, high number of strong base functional groups, and synergistic effect by introducing complex groups, which can effectively remove acidic ions, metal ions, chloride ions and other impurity ions from etherification system circulating water.

Sunresin has developed resin products and application process suitable for anthocyanin extraction from different raw materials, which can meet the purification of anthocyanin extracted from different raw materials. For example, anthocyanins from berry and floral plant sources can be used with Sunresin Seplite® LXA-86 macroporous adsorbent resin. For anthocyanins from vegetable plants, Sunresin Seplite® LXA-868M macroporous adsorbent resins can be used, which have large adsorption capacity and greatly improve the content and solubility of finished products, thereby facilitating the development of back-end applications.
