Aerosol Chemical Specifications Monitoring (ACSM)

An advanced analytical instrument designed for real-time, continuous monitoring of submicron aerosol chemical composition. It quantifies the mass concentrations of major non-refractory aerosol components, including organics, sulfate, nitrate, ammonium, and chloride, using aerosol mass spectrometry (AMS) technology.

Q-ACSM

Quadrupole Aerosol Chemical Speciation Monitor (Q-ACSM) employs a quadrupole mass spectrometer, which uses an electric field to selectively filter ions based on their mass-to-charge ratio

TOF-ACSM

Time-of-Flight Aerosol Chemical Speciation Monitor (TOF-ACSM) employs a time-of-flight (TOF) mass spectrometer, which measures the time it takes for ions to travel a fixed distance, allowing high-resolution separation and identification of aerosol species based on their mass-to-charge ratio. This advanced detection method enables faster and more precise real-time analysis
