Both LDI-TOF and MALDI-TOF Mass spectroscopy experiments of an Algerian asphaltene derived from a deposit were performed. LDI mass experiments were conducted for both linear and reflectron modes under laser wavelength/attenuation variation. The different LDI-Mass spectra show that mass distribution ...
LDI-FT-ICR can be effectively used to study CH, N1, O1, S1, O2, N2, NO and NS chemical class. However, due to its low resolving power, LDI-TOF/ TOF allows only to determine average mass of vacuum residue fractions. Both methodologies are highly sensitive to compounds with aromatic ...

relationship (R2−0.9929), a low limit of detection (400 pg), and a low limit of quantification (600 pg) of OXY. Taken together, the rapid and accurate analysis of small-molecular natural compounds in complicated samples could be achieved by the Ti3C2(OH)x-assisted LDI-TOF-MS analysis....
However, due to its low resolving power, LDI-TOF/ TOF allows only to determine average mass of vacuum residue fractions. Both methodologies are highly sensitive to compounds with aromatic groups (DBE >6).会议名称: 20th International Mass Spectrometry Conference (IMSC 2014): Abstracts: Geneva(CH)...
