lewatit®ion exchange resins and adsorbers are in widespread use in a variety of applications in the pharmaceutical and bioprocessing industries. Their end products range from food and animal feeds to active pharmaceutical ingredients (APIs) that are used in medicinal products. Ion exchange resins and adsorbers help in the treatment and cleaning of products obtained from biomass by providing support with extraction, adsorption and chromatography or through their use in demineralization and neutralization. As well as being used in cleaning, ion exchangers can therefore also help to stabilize products such as amino acids, proteins, vitamins, alkaloids and other active ingredients. In addition, ion exchange resins have become established as substrates for the transportation of active substances in either classic or ground form. Enzyme-catalyzed reactions can also be carried out with the aid of fixed enzymes, whereby the ion exchange matrix offers numerous benefits for the catalysis process.
Water of different qualities is required as a solvent in manufacturing processes in the pharmaceutical and bioprocessing industries. Lewatit®ion exchanger types can be combined to beneficial effect to meet different quality requirements for softening or demineralization of the necessary process water. OurLewaPlus®design software可以在制造的基础上建模各种组合，从而为用户提供最大的信心，即它们将获得最佳处理解决方案。它还可以通过可靠和彻底的治疗来处理来自生产设施的废水。
For these and other applications, LANXESS offers a comprehensive range of special ion exchange resins that are tailored to specific requirements.
lewatit®VP OC 1064可靠地除去具有低分子量，氯化和氮化烃的非极性有机成分，氯化和硝化烃等液体提取剂如磷酸酯的残留物。该吸附器在生物技术过程解决方案的治疗过程中也是必不可少的。
lewatit®AF5用于处理含有有机物质残留物的水，如氯化烃，MTBE，有机磷酸盐，胺，杀虫剂和其他代谢物。也可以分离活性药物成分。
优化的吸收能力和再生能力是lewatit的明显好处®adsorbents.
lewatit®PH 1074 HEP has been developed with a special pore structure and resin matrix, to enable the absorption and cleaning of organic substances with high molecular weights. It is therefore particularly beneficial in the decolorization and cleaning of biological process solutions, as is required in the production of cane sugar, for example. It can also be used reliably in the cleaning and storage of heparin and similar substances that are extracted from highly complex fermentation solutions.
lewatit®ion exchange resins make an important contribution to various downstream processes, including extraction, adsorption and chromatography, but also demineralization and neutralization of products and product flows obtained from biomass. Examples of applications include production of amino acids, vitamins and active pharmaceutical ingredients.
如今，L-赖氨酸专门根据发酵方法生产，即使已经开发了替代的有机化学合成途径。外消旋DL-赖氨酸[也称（RS） - 丙氨酸和（±）-LYSINE]具有商业重要性，作为活性药物成分的盐中的碱性成分，例如，用乙酰胱氨酸（ASA）。L-赖氨酸是用于输注肠外营养和治疗次偶杀菌性碱性病症的溶液的组成部分。赖氨酸还用于加速镇痛药的影响，特别是与布洛芬组合。强烈酸性的路易®ion exchangers in gel form, such as Lewatit®S 1668用于治疗赖氨酸。
