An Electrochemical Monitor for Air Pollutants
Analytical Letters, 1971Abstract A thin-layer electrochemical cell has been developed as a detector for air pollutants, and tested with S02-air and Cl2-air mixtures. The cell gives well-defined, reproducible signals proportional to pollutant concentrations down to 20 ppb. Two electroanalytical procedures are described for monitoring or sampling polluted air with the cell: (1)
