Ultrafast tandem ICP mass spectrometer for interference-free and high-sensitivity monitoring of transient signals (ICP-MS/MS) Ghent University
ICP mass spectrometry (ICP-MS) is a particularly powerful technique for the determination of elements at trace and ultrasonic levels. When using a quadrupole filter to separate the ions from each other according to their mass-to-charge (m/z) ratio, only modest mass resolution is obtained. Ions differing by less than half an atomic mass unit are not separated from each other, so spectral interference occurs. To avoid spectral interference, a tandem ICP-MS (ICP-MS/MS) device is equipped with a collision/reaction cell (CRC) preceded by a quadrupole filter (Q1). In an MS/MS mode, Q1 selects ...
Multicollector-Inductively Coupled Plasma Mass Spectometer (MC-ICP-MS) Ghent University
The Thermo Scientific Neptune XT multi-collector ICP mass spectrometer is an instrument developed for high-precision isotopic analysis of metals, metalloids and some non-metals. The instrument is therefore equipped with a robust and efficient ion source (the ICP, or inductively coupled plasma), a double-focusing sector-field mass spectrometer with Nier-Johnson geometry for separation of the ion beams based on the ratio of mass to charge of the respective ions and an array of 9 faraday cups for simultaneous monitoring of the selected ion beams. Under ideal conditions, a measurement ...
