AQMS-200

AQMS-300 Ozone (O3) analyzer measures ambient O3 concentration in ppb level by utilizing UV photometric absorption technology(US EPA Designation No. :EQOA–0719–253)

Principle

The concentration of ambient Ozone is proportional to UV Light Absorption since there is a significant characteristic absorption for Ozone on wavelength of 254nm.

Periodical diversion on sample flow passing through the ozone scrubber will generate reference measurement, which is compared with sample measurement to provide stable and representative result.

Ozone Scrubber The Ozone scrubber is filled with MnO as catalyst, which will convert O2 to O3 to form reference gas. Meanwhile, the presence of other components remains the same.

AQMS 400

FPI AQMS-450 carbon dioxide (CO2) analyzer measures ambient CO2 concentration by employing Non-dispersive infrared (NDIR) with gas filter correlation (GFC) method technology to realize ppm level CO2 concentration measurement.

Principle

Infrared energy emitted by light source is passed through gas chamber containing the air sample, and the quantitative absorption of energy by CO in the sample cell is measured by corresponding detector.

GFC GFC (Gas filter correlation) technology is utilized to remove interference caused by moisture and other backgrounds. Two gas filled chambers are mounted on a rotating disc, which pass through an IR beam alternately. The measure chamber is filled with nitrogen while the reference chamber is filled with high concentration CO. IR beam then passes through the sample gas cell. The difference in absorbance is measured and provides a direct output of the gas concentration.

AQMS 450

FPI AQMS-500 Sulfur Dioxide (SO2) analyzer applies UV Fluorescence Technology with photomultiplier tube (PMT) to measure SO2(US EPA Designation No.RFSA–1219–255).

Principle

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.

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 are realized.

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.

Removal of Interferences The permeation scrubber acting as hydrocarbon kicker removes aromatic hydrocarbon such as xylene and naphthalene which causes interference. Optical filtering are employed to improve the rejection of interference from high nitrogen oxides.

PMT System The characteristic fluorescence of SO2 is received by the photomultiplier tube and converted into an electrical signal. The number of electrons is increased by the photomultiplier system and the current or voltage is collected by the anode.

FPI AQMS-600 Nitrogen Oxides (NO-NO2–NOx) analyzer utilizes chemiluminescence technology indicated by US EPA as federal reference method for monitoring on multiple forms of nitrogen oxides(US EPA Designation No.RFNA–0819–254)

Principle

Nitrogen oxides in ambient are measured indirectly by photometrically measures the light intensity, resulting from the chemiluminescent reaction of Nitric Oxide (NO) with Ozone (O3). NO2 is first quantitatively reduced to NO by means of a converter. NO, which commonly exists in ambient air together with NO2, passes through the converter unchanged causing a resultant total NOX concentration equal to NO+NO2.
