Abstract
In ultraviolet absorption spectroscopy, absorption cross section (ACS) is a parameter important for calculating ozone concentrations. In this work we have determined the ACS at the room temperature and normal pressure. The ozone concentration has been recorded in the region 450–989 ppm, using a compact aluminium gas cell of 5 cm optical path length. We have also compared the results derived with the ratiometric and non-ratiometric methods based on the Beer–Lambert law. Our experimental results demonstrate that the non-ratiometric method can compete with the ratiometric method whenever the measuring times are relatively short.
