Natural polymers, humic acid and lignins, were investigated by laser desorption (LD) Fourier transform mass spectrometry. In the vapor phase under LD conditions only positive ions of humic acid were observed up to m/z 700. Under the same conditions all the lignins investigated prefer to form negativ

Molecules chemisorbed on a platinum single crystal are desorbed by a pulsed laser, ionized by an electron beam or multiphoton ionization, and detected by Fouriertransform mass spectrometry (F.t.m.6.). Laser desorption of ethylene, methanol, cyanogen, benzene and naphthalene is described. In all case

The first mass spectrometric analysis of a new class of hydrocarbon dendrimers that result from a convergent synthetic approach is reported. Molecular weights of a series of phenylacetylene dendrimers (715 to 14776 u MW) are characterized by ultraviolet matrix-assisted laser desorption (MALDltime-of

## Abstract Detailed structural information can be obtained without derivatization for a variety of naturally occurring pteridines by using laser desorption Fourier transform mass spectrometry. Laser desorption provides a soft ionization technique for these non‐volatile compounds and generates char
