Abstract: Chemical composition of aerosol particles is generally determined by gas- and liquid-chromatographic techniques, mostly with mass spectrometric detection. Use of liquid chromatography (LC) has increased in atmospheric analysis due to the recently recognized importance of highly oxidized compounds in aerosol formation and growth, improved separation efficiency of the columns, and high-resolution mass spectrometric detection.Summary: Atmospheric particles that can be natural or anthropogenic, are defined as a suspension of fine solid or liquid particles in air. They are either emitted or formed in the atmosphere and their particle sizes affect their transport and deposition. Their most important impacts, such as respiratory health hazards, visibility reduction, and climate effects are dependent upon the particle size that ranges from a few nanometers to a few hundred micrometers.References: Robinson N.H., Hamilton J.F., Allan J.D., Langford B., Oram D.E., Chen Q., et al.
