• intros：{"brand_intro":"Cytiva（原GE Healthcare生命科学部）是全球层析技术的绝对领导者，总部位于美国，2020年从GE独立后并入丹纳赫集团。其历史可追溯至1950年代的Pharmacia，是Sepharose、Sephadex等经典填料的发明者。Tricorn系列是实验室级层析柱的标杆，以极低死体积和超高柱效闻名。品控遵循GMP标准，每根柱子出厂前均经过压力测试和柱效验证，是药企QC和研发部门的标配。","product_intro":"Tricorn 5/50（内径5mm，柱长50mm）是微量层析的经典型号，柱体采用高透聚丙烯，搭配精密加工的端盖和密封圈。核心卖点是其死体积仅为柱体积的1%，可实现高分辨率分离。适用于蛋白组学、微量抗体纯化等。竞品对比中，其柱效（理论塔板数）可达20000 N/m，远超国产柱，但价格也最高。用户常评价\"用一次就回不去了\"。","key_specs":{"柱体积":"约1mL（5mm内径×50mm长度）","材质":"高透聚丙烯，端盖为PEEK","最大耐压":"1.0MPa，适配AKTA等中高压系统","死体积":"小于10μL，适合高分辨率分离","适配填料":"Sepharose、Sephadex、Superdex等Cytiva原厂介质"}}
