Description
AQMS-500 Sulfur Dioxide Analyzer
Product overview
AQMS-500 measures the intensity of the characteristic fluorescence released by SO₂ in an ambient air sample contained in the gas chamber when the air sample is irradiated by ultraviolet light passed through the chamber.
Removal of Interferences
The permeation scrubber acting as hydrocarbon kicker removes aromatic hydrocarbon such as xylene and na-phthalene which causes interference. Optical filtering are employed to improve the rejection of interference from high nitrogen oxides.
UV Source
The pulsing of the UV source lamp serves to increase the optical intensity whereby a greater UV energy throughput and lower detectable concentration arerealized.
PMT System
The characteristic fluorescence of SO₂ is received by the photomultiplier tube and converted into an ele-ctrical signal. The number of electrons is increased by the photomultiplier system and the current or voltageis collected by the anode.
Data Storage and Analysis
Stored data are easily retrievable through the serial or Ethernet port via PC client software, allowing operators to perform predictive diagnostics and enhanced data analysis by tracking parameter trends.
