詳細介紹
Bio-rad伯樂Aminex® HPLC 色譜柱
Aminex® HPLC Columns
由聚苯乙烯二乙烯苯樹脂填裝而成的Aminex HPLC 柱，具有良好的高壓及pH穩(wěn)定性、高柱效和選擇性。Aminex HPLC柱通過離子調節(jié)分配層析技術分離混合物，這種技術是根據(jù)多種不同的化學特性分離分子。離子調節(jié)分配層析技術的分離機制包括離子排阻、離子交換、正相和反相分配、分子量排阻和配體交換。根據(jù)層析的物理和化學特性， 可選擇使用一個或多個分離機制。Aminex 柱是工業(yè)界普遍使用的，用來分析碳水化合物、有機酸、有機堿和其它包括肽和核酸的有機小分子的標準產品。用Aminex 柱分離復雜混合物需要使用簡單等流相（常用水），并要求精確控溫。
研究過程中，樣品可重復的保留值和分辨率是至關重要的。不同批次間及不同柱間的測試證明Aminex 柱是值得信賴的產品。
Aminex 柱的使用壽命長，并能保持上百次試驗的可重復性。耐用的層析柱避免了頻繁更換柱引起的數(shù)據(jù)變化和高成本。
Aminex 柱應用實例
• 木漿水解產物分析
• 玉米汁成分分離
• 大鼠肝流出液層析圖譜
• 從cheddar 奶酪中分離有機酸
