Time-of-flight ICP

Figure 5.2 Overview of ICP-MS instrumentation quadrupole-based ICP-MS with and without colli-sion/reaction cell, sector field ICP-MS with single ion collector (ICP-SFMS) and multiple ion collector ICP-MS (MC-ICP-MS) and time-of-flight ICP-MS.

The axial time-of-flight ICP-MS was introduced in 1998 by LECO (Renaissance, LECO, St. Joseph, MI) and has been commercially available for several years. A schematic of the ICP-ToF-mass spectrometer is shown in Figure 5.11. The analytical performance of this mass spectrometer, which allows 25 000 spectra to be measured per second and is thus faster than a quadrupole ICP-MS,... 

The purposes of this paper are to report on our efforts to evaluate the real world precision of laser ablation time of flight ICP-MS (LA-TOF-ICP-MS) replicate measurements on NIST standards and archaeological materials, and to...

Recently, ICP time-of-flight (ICP-TOF) mass spectrometers have been commercialized (Figure 45). The TOF analyser has a number of advantages over other analyzers used for ICP-MS. The fact that all masses in the spectrum can be monitored simultaneously is the main attraction for many ICP-MS users. Even for simple multielement analysis, scanning analyzers suffer from a decrease in sensitivity as the number of ions to be monitored is increased. The fact that over 30000 simultaneous mass spectra per second can...
