New evidence for the molecular–chemical diversity of potato plant rhizodeposits obtained by pyrolysis–field Ionisation mass spectrometry

Abstract

Py-FIMS was well suited to detect the molecular-chemical diversity of potato plant rhizodeposits and, compared with traditional a priori analytical methods, provided detailed evidence for significant differences in the composition of rhizodeposits depending on growth stage and diurnal period.

Hydrothermal Carbonization of Biomass Residues: Mass Spectrometric Characterization for Ecological Effects in the Soil-Plant System

“…However, there are early indications of possible toxicological effects such as germinal and growth inhibition (Busch et al, 2011), which strongly call for a detailed characterization of the chemical composition of the complex hydrochar matrix. By the application of a nontargeted analytical method such as pyrolysis‐field ionization mass spectrometry (Py‐FIMS) (Schulten et al, 1989; Franke et al, 2006, 2007; Schlichting and Leinweber, 2009), it appears possible to find a priori unexpected compounds other than the well‐known environmental contaminants referred to above.…”
