摘要：

Direct spectroscopic methods are not hampered by wall losses, are highly specific, have a potential for real time detection and offer the possibility to measure several species simultaneously in one experiment. This is demonstrated for the determination of NH3, NO and SO2 in ambient air by a differential optical absorption spectroscopy (DOAS) technique in the spectral region 207-221 nm. Detection limits were 1 ng/g or better.
