Gas sensing in industry by tunable diode laser spectroscopy (TDLS)

TDLS has become the best available technology ... Tunable diode laser spectroscopy (TDLS) can measure the concentration, temperature and pressure of various gases in-situ under harsh conditions with good time resolution, sensitivity and selectivity. High temperatures, high pressures and particle-laden gas streams can be dealt with. TLDS has become the best available technology and state-ofthe art in several demanding metrology applications like the determination of trace moisture in HCl or the measurement of NH3 slip directly in a stack in DENOX plants for closed loop control. The book reviews the basic principles of the technology and presents applications grouped by target species like H2O, NH3, O2, CO, CO2 and applications like petrochemical industry, semiconductor industry, steel making and healthcare. The book also contains a list of suppliers of commercial instruments.
