FPI’s standard stationary AQMS consists of complete sets of analyzers that apply general online reference and equivalent methods for monitoring regular air quality parameters; the priority of these stations is to generate reference and representative point-wise AQI in such region. These stations and data are considered state-level standard data to be published.

VOC-115 analyzer uses dual-column, dual-valve switching technology, and hydrogen flame ionization detector(FID)technology for the detection of methane and non-methane hydrocarbons.
VOC-210 adopts cold temperature enrichment and high-temperature thermal desorption technology for sample enrichment, and the detector adopts FID technology to measure BTEX.

FPI AQMS-200 dynamic dilution calibrator utilizes two mass flow controllers to perform standard zero and span calibration with up to 4 gas sources.

LAMPAS adopts the single-particle aerosol time-of-flight mass spectrometry that can measure single particles' chemical composition and size in real-time and respond rapidly to a sudden source of pollution. Due to its versatility, LAMPAS is generally used to determine pollution sources in the urban, remote, and marine environment or verify the PMF module's accuracy to provide data reports to the environmental agency.

LAMPAS-3.0 consists of a sample injection system, diameter detector, laser ionization system, and TOF-MS analysis system. Aerosol particles are accelerated into the vacuum chamber via a differential vacuum chamber, the aerodynamic diameter of the particle is detected by the dual laser beam. Meanwhile, ionization laser is triggered, ionized cation and anion are finally analyzed by TOF-MS.

FPI AQMS-300 Ozone analyzer measures ambient O3 concentration in ppb level by utilizing UV photometric absorption technology.

FPI AQMS-400 carbon monoxide (CO) analyzer measures ambient CO concentration by employing nondispersive infrared with gas filter correlation method technology.
