icpTOF的优越性能

icpTOF电感耦合等离子体-飞行时间质谱耦合了Thermo Scientific公司的 iCAP RQ平台（包含离子源和真空接口）和TOFWERK高性能飞行时间质谱分析仪。iCAP RQ平台提供了多类型的样品进样方式，高强度并稳固的ICP，更加简单的椎体和离子电镜维护程序和Q-cell科技。飞行时间质谱分析仪在保证跟四级管（QMS）同等灵敏度的同时，为icpTOF增加了快速全谱分析，更宽的线性动态范围和高达6000的质量分辨率。鉴于其快速全谱图采集和所有元素同位素的同步分析，icpTOF是单颗粒多元素分析和快速激光蚀刻成像的理想检测器。

  • All the elements. All the time.
    icpTOF记录全谱图以提供回溯分析,因此 您不会错过任何分析物或干扰信号。
  • 高质量分辨率
    icpTOF 2R高达6000的质量分辨率让排除干扰离子更加容易。
  • 精确的同位素比率
    icpTOF可同时测量所有同位素,从而最大程度上消除离子源和进样过程扰动对测量结果的影响。分析精度趋近于统计限制。
  • 高速检测
    icpTOF每隔30微秒就可记录一张全谱图,使其成为快速瞬态信号(如单个纳米颗粒,流体包裹体和单激光脉冲烧蚀)的最佳检测器。
