Levoglucosan concentration in ice core samples from the Tibetan Plateau determined by reserve-phase high-performance liquid chromatography-mass spectrometry
Levoglucosan is a unique marker for biomass burning that can be transported in the atmosphere and preserved in archives such as ice cores. A new method to determine the concentrations of levoglucosan in Tibetan ice-core samples using high-performance liquid chromatography with electrospray ionizatio...
