Aarhus University wants to purchase Aerosol Devices PAL 700 automatic sample extraction system for extraction of samples collected with Series 110A sequential aerosol spot sampler. The Aerosol Devices PAL 700 automatic sample extraction can be coupled directly with an existing ultrahigh performance liquid chromatograph — quadrupole time-of-flight mass spectrometer (UHPLC-qTOF-MS) for automatic sample injection and molecular analysis. The combined system for sequential aerosol sampling and automatic extraction will be used for time-resolved investigations of organic composition of aerosols collected from ambient air and laboratory chamber studies. The Aerosol Devices PAL700 automatic sample extraction system for use with a Series 110A sequential aerosol spot sampler is the only commercially available system on the market, which can perform this task.
