- •
FTIR and elemental analysis demonstrate the strong aliphatic character of lipids.
- •
Lipids are of rather low molecular weight and exhibit low oxygen content.
- •
Lipids participate in the fluorescence of lignites and humic substances.
- •
EEM lipid spectra have the character of fingerprints.
- •
The typical maxima of lipid fluorophores lie in the range 260–275/370–440 nm.
