The fundamental physical processes of mid infrared laser ablation in the context of laser desorption mass spectrometry were investigated. Understanding the mechanisms of infrared laser desorption and ablation can lead to improvements in these techniques and expand their applications. Particles were generated from glycerol irradiated at atmospheric pressure using a tunable infrared laser at wavelengths between 2.6 and 3.8 µm. The wavelength dep...

Extensive researches have been focused on the analysis of organic compounds in coals at the molecular level to reveal the characteristics of coals with different ranks and/or origins. Mass spectrometry, in association with a variety of sample inlet systems, has revolutionized the analysis of complex mixture like coals and should be the most rapidly developed analytical technology in the last 20 years. Various ion sources have been developed th...
