We developed new laser desorption ionization method(DIUTHAME: Desorption Ionization Using Through Hole Alumina MEmbrane)as matrix-free ionization method.
Recent interest in fieldable mass spectrometric applications has spurred a great deal of research into the development of a miniature mass spectrometer(MS).
In recent years,carbonate clumped isotopes(expressed as Δ47,quantifying the excess abundance of CO2 of mass 47(13C18O16O)in carbonate relative to the theor
Lipids are important structural components of biological systems,and the double bond positions of lipids play critical roles in their biochemical and biophy
