A mass spectrometer determines the mass of a molecule by measuring the mass-to-charge ratio (m/z) of its ion. Ions are generated by inducing either the loss or gain of a charge from a …

Mass spectrometry has revolutionized proteomics in a manner analogous to the impact of massively parallel DNA sequencing on genomics and transcriptomics. In this study, high …

A mass spectrometer is whatever operates by process that could be used to produce a mass spectrum, no matter how different its design and processes may be from those of any other …

First mass spectrometer with solids injection probe sold to UNITED STATES PUBLIC HEALTH SERVICE LABORATORIES in Cincinnati, OH. Used by Dr. Richard Kupel to study the …

The use of electronics to revolutionize the mass doublet method of determining relative atomic masses, effectively turning mass spectrographs into mass spectrometers.

May 26, 1998 · Thomson's protégé, Francis W. Aston of the University of Cambridge, designed a mass spectrometer in which ions were dispersed by mass and focused by velocity--which …

Today, units of atomic mass (atomic mass units or "amu's") are often referred to as "daltons" in honor of John Dalton. His analytical apparatus could appropriately be called the world's first …

A mass spectrometer determines the mass of a molecule by measuring its mass-to-charge ratio (m/z). Ions are generated by inducing either the loss or gain of a charge from a neutral species.

A mass spectrometer determines the mass of a molecule by measuring the mass-to-charge ratio (m/z) of its ion. Ions are generated by inducing either the loss or gain of a charge from a …

From about 1915-1920 on, mass spectrometry developed along two main lines: one concerned with the precise determination of masses, and the other concerned with measuring the relative …
