In a Kendrick mass analysis, the Kendrick mass defect is plotted as function of nominal Kendrick mass for ions observed in a mass spectrum.

Surface-based mass analysis has seen a resurgence in the past decade, with new MS technologies focused on increasing sensitivity, minimizing background, and reducing sample preparation.
13.
These differences indicate that individual variation can be influential in the size distribution of debitage and should be kept in mind if mass analysis is being employed.
14.
But the inventory alone promises to be a daunting task that would require new mass analysis techniques and computerized databases rivaling the effort to map the human genome.

Egg-mass analysis shows that in clutches produced at the beginning of the breeding season, the second egg in a nest were, on average, 1.5 % heavier than the first.
16.
The eluent from the chromatography stage can be either directly introduced to the mass spectrometer through electrospray ionization, or laid down on a series of small spots for later mass analysis using MALDI.

SIRCAMS is part of the RCUK post-translational modifications in intact human histones using top-down ECD, top-down identification of proteins from complex mixtures, as well as accurate mass analysis of oligonucleotide DNA strands ( 40 bp ).

The American theoretical physicist John Archibald Wheeler coined the term " wormhole " in 1957; the German mathematician Hermann Weyl, however, had proposed the wormhole theory in 1921, in connection with mass analysis of electromagnetic field energy.

A Kendrick mass analysis is often used in conjunction with a Van Krevelen diagram, a two-or three-dimensional graphical analysis in which the elemental composition of the compounds are plotted according to the atomic ratios H / C, O / C, or N / C.

Ahler ( 1989 ) conducted an experimental replication under some technological settings and classified debitage into five groups according to their size, Discriminant analysis ( by SPSS DISCRIMINANT function ) was applied to compare mass analysis data sets for these five experimental data groups.
