Waters XBridge色谱柱
沃特世于1999年首次推出XTerra 色谱柱，其专利的有机与无机杂化颗粒技术[Hybrid Particle Technology，HPT] 突破了硅胶基质填料的重要限制，尤其是在高pH值条件下易于水解的不稳定性。2005年Waters推出了基于其第二代杂化颗粒专利技术（称为BEH TechnologyTM）的新系列色谱柱品牌，分别为ACQUITY UPLC BEH和XBridgeTM，建立了色谱史上新的里程碑。
BEH TechnologyTM?成功地将色谱柱在高pH值条件下的稳定性提高了一个数量级，具有最高的柱效，可提供更高层次的色谱性能，使之当之无愧地成为液相色谱领域的新标杆。
XBridge色谱柱专门为液相色谱方法开发和快速纯化而设计，用户能够在整个pH范围内使用种类多样的流动相体系和很宽的温度范围进行方法开发，从而建立稳定耐用的分析方法。XBridge OBD 制备色谱柱在高pH条件下分离和纯化碱性化合物能够得到更高的纯度，并且上样量可提高几十倍。
XBridge色谱柱具有非常稳定的性能和更长的寿命，即使在最苛刻的条件下。它采用革命性的创新技术生产，而且按照行业内最严苛的质量标准进行质量控制，因此成为用户针对挑战性色谱分离的值得信赖的解决方案。
XBridge色谱柱特点
◆ HPLC方法无间隙转换到UPLC
◆ 极端pH条件下的更长的寿命和可靠性
◆ OBD制备柱的卓越性能
◆ BEH颗粒具有和超纯硅胶相当的柱效
