詳細摘要：MLD packings （MLD = monolayer dense） are very stable solide supports, known in the literature as “mixed self-assembled monolayers （SAM）". They can be used both for basic and acidic compounds in a re

詳細摘要：UltraSep ES PHARM and UltraSep ES PHARM SPEZIAL are high selective HPLC-packings, first of all developed to analyze pharmaceutical products, which are often very polar and strong basic. The extreme sm

詳細摘要：Special columns are a central concern in our company. With an appropriate column you can solve nearly all separation tasks, not laboriously by high plate numbers, but simply by tailor made selectiviti

詳細摘要：In addition to our range of silicagels we are offering sulfonated styrene-divinyl resins （GROM Polymer Phases） for the analysis of organic acids, carbohydrates, und sugar alcohols. The resins are ava

詳細摘要：All the cation exchangers offered possess chemical fixed exchanger groups and indicate a very good stability within acid media. Weak cation exchangers bear carboxylic groups, strong exchangers sulfon

詳細摘要：These anion exchangers are so called ?permanently loaded“ ion exchangers. They exhibit the excellent performance of silicas and the good stability of RP-phases, which leads to low costs.
