HPLC
High-Performance Liquid Chromatograph

The High-Performance Liquid Chromatograph (HPLC) is an in situ ground-based analyzer that is used to separate and identify components within a sample of air or mixture. It achieves this by injecting a liquid within the sample causing different flow rates for each component as they flow out of the column. As each component exits the column, their concentrations are measured at a high resolution. In Earth science research, HPLC is typically used to determine various trace species in the atmosphere such as formaldehyde, hydrogen peroxide, and volatile organic compounds (VOCs). HPLC is commonly used for laboratory analysis and ground-based measurements, but it can be used for airborne measurements as well.
