Unresolved discrepancies between isotope ratio measurements are not uncommon and have even slowed down the revision of the International System of Units, explains Juris Meija. Leading up to the ...

This Primer summarizes the underpinning theory and experimental process in a SIMS measurement. It describes the typical data outputs and data analysis principles, using illustrative examples to show ...

Thermo MAT 253 Plus isotope ratio mass spectrometer equipped with universal CNOS and HD collectors, ConfloIV interface, GC IsolinkII, and Trace GC 1310 to analyze isotopic composition (C & H) of ...

The CUBES-SIL lab has three magnetic sector, gas-source, isotope ratio mass spectrometers designed to measure the relative abundance of stable isotopes of light elements and molecules. These ...

Isotopic analysis primarily involves the separation of isotopes based on the significant differences in mass. The method is effective for identifying the isotopic signature within the inorganic and ...

Mass spectrometry (MS) is an analytical technique used to identify and quantify molecules based on their mass-to-charge ratio (m/z). It provides valuable information about the chemical composition, ...

A quadrupole mass analyser designed for fusion research combines radiation hardness with the ability to distinguish between ...

Tradeoffs between resolution, sensitivity, and speed are inevitable in chemical analysis but strides are being taken to boost resolution and to improve “qual-quant” methods that enable researchers to ...

Mass spectrometry measures the mass-to-charge ratio of ions by ionizing chemical compounds to produce charged molecules. A typical mass spectrometer consists of three parts: a detector, a mass ...
