Ultraviolet gas analyzer is an optical instrument that determines gas concentration from ultraviolet absorption, fluorescence, or photoionization signals produced when a sample stream is irradiated in the UV band. In absorption photometry the device implements Beer–Lambert spectroscopy with a UV source, a defined optical path, spectral selection, and a detector to quantify attenuation on rovibronic bands; non-dispersive UV (NDUV) uses interference filters or gas-correlation optics to isolate features, while differential optical absorption spectroscopy (UV-DOAS) employs a spectrograph and numerical fitting of structured cross-sections to separate fine molecular structure from broadband extinction. Ozone analyzers use photometry at the 253.7 nm mercury line with alternating scrubbed/unscrubbed paths to form a ratio measurement; sulfur dioxide is measured by UV absorption or by UV-excited fluorescence detected at characteristic emission bands; aromatic VOCs exhibit strong π–π* absorption in the near-UV; elemental mercury is measured by resonant UV absorption. Photoacoustic UV instruments convert absorbed energy into an acoustic signal detected by microphones or quartz tuning forks, and photoionization detectors use UV lamps with defined ionization energies to generate charge pairs proportional to the concentration of easily ionized organics.
Core technologies comprise stabilized UV emitters—low-pressure mercury lamps, deuterium lamps, xenon flash lamps, and AlGaN deep-UV LEDs—beam conditioning, and an interaction region constructed as a single- or multi-pass cell with UV-transparent windows in fused silica, CaF₂, or sapphire. Spectral selection is realized with dielectric filters, monochromators, gratings, or miniature Czerny–Turner/FT spectrometers; detection uses silicon photodiodes for near-UV, solar-blind AlGaN or SiC photodiodes for deep-UV, photomultipliers for low-light fluorescence, and thermoelectrically cooled HgCdTe or InAsSb where extended response is required. Signal chains implement chopping or electronic modulation with synchronous detection to suppress source and 1/f noise, temperature and pressure sensing for spectral normalization, and fitting engines that apply tabulated cross-sections and line-shape models to retrieve concentrations while accounting for interfering species, water vapor continuum, and window fouling baselines. Sample handling spans extractive cells with filtration, condensate control, and corrosion-resistant wetted materials for acid gases, to in-situ and open-path heads for path-averaged measurements; materials and finishes are selected to minimize adsorption memory for polar species.
Manufacture follows opto-mechanical and gas-path integration with electronic assembly and factory calibration. Optical benches are machined for stability and aligned to preserve source–detector geometry and path length; multipass cells are assembled with precision mirror spacing, low-scatter interiors, and helium-leak testing; gas manifolds are passivated and fitted with calibrated pressure and temperature transducers. UV sources are bonded, aged, and intensity-screened; detectors are mounted with thermal management and, where applicable, windowed shields; spectrometers are wavelength-calibrated using internal references or emission lines. Control and acquisition electronics comprise precision lamp/LED drivers, low-noise transimpedance stages, ADCs, and embedded processors implementing modulation waveforms, diagnostics, and data reduction. Calibration uses certified gas standards or permeation/photolytic generators to establish zero, span, linearity, and cross-interference coefficients across the operating range; environmental qualification applies temperature–humidity cycling, vibration, shock, and contamination challenges to quantify drift and recovery.
Applications include continuous emissions monitoring of SO₂, NO₂/NOₓ (by UV-DOAS), HCl, HF, NH₃, and Hg⁰ on stacks and ducts; ambient and indoor air networks where ozone and aromatic VOCs are tracked photometrically; process monitoring of bleaching gases such as ClO₂ and of refinery, petrochemical, and semiconductor lines carrying UV-active species; safety monitoring in confined spaces for ozone and SO₂; and open-path fence-line surveillance for benzene and other aromatics. Across these uses, defining attributes are spectral selectivity in the ultraviolet bands of the target, stability of the optical and sampling stack under the thermal and chemical environment of the stream, and metrological performance expressed by detection limit at stated averaging time, T₉₀ response, linear dynamic range, span/zero drift, and resistance to cross-sensitivities.
