Analysis of soluble components in coals and interpretations for the complex mass spectra.
Rapid Commun Mass Spectrom
March 2017
Rationale: The deduction of useful information from the mass spectra of a complex mixture like coals remains difficult, which limits the clean and efficient utilization of coals. It is necessary to explore the data interpretation methods for mass spectra and visualize the analytical data of coals for industrial utilization such as feedstock selection.
Methods: Coal sample and methanol were mixed and heated to 310 °C and kept at that temperature for 2 h.
Article Synopsis
- - The study analyzed 24 raw propolis samples using a method called surface desorption atmospheric pressure chemical ionization mass spectrometry (SDAPCI-MS) without needing to prepare the samples beforehand.
- - The most significant signals were found within specific mass ranges (70 to 500 m/z and 200 to 350 m/z), with principal component analyses revealing that color was linked to the first two principal components, while climate zones had no connection to the samples.
- - Key compounds like chrysin, pinocembrin, and quercetin were identified quickly (within 3 minutes) using advanced mass spectrometry techniques, indicating that SDAPCI-MS is effective for fast and reliable analysis of propolis.
