Structure and Operating Principles of a Gas Analyzer Using UVF. The gas analyzer using UVF flows a sample gas into a fluorescence cell, and the UV fluorescence (Equation 1) caused by the UV radiation and the SO 2 in the fluorescence cell is selectively transmitted through an optical filter and detected by a photodetector to measure the gas concentration (Figure 1).
The analyzer has a high-sensitivity UV detector with proven performance at 0.05 ppb (V/V) as an atmospheric SO2 monitor. Eight spectral Eight spectral mirrors are combined to change the excitation light to a monochromatic beam to minimize the interference due to moisture and otherAtomic fluorescence spectroscopy analyzer for determination of mercury. Fluorescence spectroscopy (also known as fluorimetry or spectrofluorometry) is a type of electromagnetic spectroscopy that analyzes fluorescence from a sample. It involves using a beam of light, usually ultraviolet light, that excites the electrons in molecules of certain compounds and causes .1.3 THEORY OF OPERATION: UV FLUORESCENCE METHOD The SO2 analysis is based on the principle of the characteristic fluorescence released by the sulfur dioxide molecule when it is radiated by ultraviolet light of 190-230 nm. SO2 absorbs light in this region of the spectrum without any quenching by air or most other molecules found in polluted air.
