LAMPAS-3.0 Ambient PM TOF-MS FastTrack System
LAMPAS adopts the single-particle aerosol time-of-flight mass spectrometry that can measure the chemical composition and size of single particles in real-time, and respond rapidly to sudden source of pollution. Due to its versatility, LAMPAS is generally used for determining pollution source in urban, remote and marine environment or verifying the accuracy of PMF module to provide data report to environmental agency.
LAMPAS-3.0 consists of sample injection system, diameter detector, laser ionization system and TOF-MS analysis system. Aerosol particle are accelerated into vacuum chamber via differential vacuum chamber, the aerodynamic diameter of particle is detected by dual laser beam. Meanwhile, ionization laser be triggered, ionized cation and anion are finally analyzed by TOF-MS.
