Mass Spectrometry Wiki, based on Wikipedia Mass Spectrometry Category. It is the IUPAC-sponsored project to update the standard terms and definitions for mass spectrometry. Anyone can edit entries after logging in. 

Notwithstanding the efforts of groups attempting to precisely define acceptable practices and requirements, [20] confusion still exists on the differences between definition of the terms high resolution and accurate mass. [21] High resolution, as in any context, implies the ability to make confident measurements of small differences. In mass spectrometry, high resolution implies the ability to measure the small differences deriving from different elemental compositions, which have the... 

Indeed, there is almost no book using the term mass spectroscopy and all scientific journals in the field bear mass spectrometry in their titles. You will find such highlighted rules, notes and definitions throughout the book. This more amusing one - we might call it the zeroth law of mass spectrometry - has been...

The intention of this section is to provide to the reader a rapid and comprehensive reference for the most common definitions and acronyms used in mass spectrometry. Currently lUPAC has initiated a project to update and extend the definitions of terms related to the field of mass spectrometry. The definitions presented here (Table 1.6) are from the third draft document [16]. For more details and the latest updates, please consult www.msterms.com. 

Measurement of the amount of substance The definition of primary methods implies that a complete uncertainty statement can be expressed in terms of the SI units without reference to a standard of the quantity being measured. Only a very limited number of methods (isotope dilution with mass spectrometry, coulome-try, gravimetry, titrimetric analysis) comply with these criteria and only these can be used for the determination of the purity of materials used in the preparation of (primary) RMs. 

Standard terms and definitions relating to mass spectrometry can be found in Chapter 12 of the IUPAC Orange Book Compendium of Analytical Nomenclature [1] and in other sources [2-A],... 

A full list of old and new terms related to the field of mass spectrometry is given on the msterms.com web site [5], The goal of this site is to provide information about and discussion of the IUPAC sponsored project to update and extend the standard terms and definitions for mass spectrometry. This site also contains a compilation of the latest draft terms, related discussion and Orange Book terms.
