高性能的分子式鉴定方案
布鲁克公司高性能的TOF-MS质谱系统包括众多专业应用软件,例如分子式确认软件,分子式生成软件,多目标物筛查软件,生物标志物发现软件和完整蛋白分析软件等等。
布鲁克公司micrOTOF II 质谱仪在性能和多应用领域方面代表了同类高分辨质谱仪的金标准,其卓越的质量准确度和分辨率,保证了分子式鉴定的可靠性。与任何HPLC、UHPLC、CE甚至GC联用,均可保证获得高精度质量窗口的高分辨提取离子流色谱图。
全新的离子光学聚焦器件结合改进的校正程序,保证了micrOTOF II 分辨率大于16,500 FWHM并且质量准确度小于2ppm的出众性能,使得micrOTOF II 成为行业标准。
TIP 真实同位素峰形和SmartFormula 算法
传统算法只采用测定的分子量来推测分子式,而Bruker公司micrOTOF II 质谱仪在此基础上加入第二维信息,即真实同位素峰形。化合物测定的同位素峰型与真实同位素峰形相匹配,从而显著提高了鉴定分子式的可信度。
功能强大的应用软件
Bruker 公司的Compass 软件包整合了半岛游戏平台官网入口网址
控制、数据采集和数据处理等软件,具有非常友好和易用的用户操作界面。只需简单的方法设置,LC/MS工作流程即可完全自动化进行。Compass软件包使得micrOTOF II 质谱可与所有常见HPLC和nanoLC等分离技术联用,满足客户不同应用的需求。
micrOTOF II 质谱系统适应开放式管理环境的需要,可以满足多用户、多类型样本的分析要求。
