The Laboratory of Physical Meteorology (LaMP) wishes to acquire a high-resolution mass spectrometer for the online characterization of the chemical composition of atmospheric particle embryos and their gaseous precursors. This instrument is intended to integrate an experimental device that will be operated continuously, with sequences alternating measurements in real atmosphere and semi-controlled enclosure.
