文摘

Sensitive sulfur dioxide sensing system based on the broadband absorption spectroscopy in wavelength range of 198–222 nm was developed. Sulfur dioxide concentration detection limit of 17 ppb per meter was achieved. Sensitive and uncertainty improvements of more than 10 times were achieved comparing to that based on absorption band in 300 nm. Home-made LabVIEW-based software was developed.
