Based on wet chemical sampling and long path absorption photometry, an instrument for on-line monitoring atmospheric nitrogen dioxide was developed. The instrument contained three parts, including external sampling unit, transfer unit, and detection unit. The external sampling unit was composed of three spiral coils connected in series, in which NO₂ was selectively absorbed. It was protected with thermal insulation and light shielding, and no inlet line was used. The transfer unit used a diaphragm pump and a peristaltic pump to control gas sampling and solution delivery through a pipeline system. The detection unit included a LEDs light source, a long path flow cell, and a spectrometer to quantify the azo dye generated by NO₂. By optimizing the measurement wavelength, the accuracy and stability of the instrument were improved, and the absorption liquid formula was changed to reduce the maintenance requirement. The instrument had a high absorption efficiency (>99.5%), a low detection limit (40 ng/m³) at a response time of 4 min, and a measurement uncertainty of ±10%. With a wide measurement range from 40 ng/m³ to 410 μg/m³, it could be used to monitor the background environment atmosphere and the pollution source. The interference test showed that the main interference species in the atmosphere had negligible influences on the instrument. Compared with the commercial nitrogen oxide analyzer (Thermo 42i), the coefficient of determination R² reached 0.98, and the difference between the two measurement results was only 3%, showing high accuracy and reliability.
