The review describes on-line derivatization/degradation methods employed in mass spectrometry to solve some structural and analytical problems. Advantages and applications of various positions of reaction systems connected mainly to a mass spectrometer or a gas chromatograph/mass spectrometer are considered. Among these are reaction systems connected directly to the mass spectrometer (reaction ...
We describe assembly and optimization of a continuous flow nanoelectrospray source for high-performance analysis on a routine basis. It is derived from an inJection adaptable Fine Ionization Source ("JaFIS"), previously shown to be durable and easy to use (Geromanos, S.; et al. Rapid Commun. Mass Spectrom. 1998, 12, 551-556) and now modified for maximum sensitivity. Proper design, manufacturing...

A specialized isotope mass spectrometer for determining the isotopic ratio of lithium by ERIAD (electrospray with atomization in an ion source) is described. The device uses a Mattuha-Herzog-type analyzer double focusing to use beams large spread energy and simultaneous registration signals both isotopes ( 6 Li 7 Li), two-channel receiver based on doublet microchannel plates. gas-dynamic interf...
