赛默飞新一代 253 Plus 是经典 MAT 253 系列质谱仪的全新升级版。它再一次重新定义了高性能同位素比质谱仪。只有 Thermo Scientific 10 kV IRMS 技术才能体现真正意义的稳定性、线性和灵敏度。253 Plus 技术创新保证了高样品利用率、高稳定性,极低本底以及高信噪比,保证了最小样品量条件下前所未有的高精度。
与经典 MAT 253 系列相比,它的创新性体现在:
l 全新的1013欧姆放大器技术,为极小信号离子束(例如 m/z 47、48 和 49)和极低丰度样品提供了强大技术支撑,特别适用于二元(clumped)同位素分析。
l 新型的接收器排布,使得在最高强度的离子源负载下,也可有效降低散射离子背景;同时采用半质量检测器定位,进行基线监测
l 新型的磁铁设计,改善了峰形和稳定性的同时,也确保了极低信号强度下的长积分时间和最高分析精度。
l 全新内置的 LIDI(长积分双路进样)工作流程,使得样品利用率提高 3 倍, 样品量降低 3 倍,更节省测量时间,保证了终极的高精度
