Moreover, some small shifts in the wavelengths are observed between the two sets of data in the range of the Huggins bands where the vibrational structure is observed. In addition, Yoshino et al. (1988) gave measurements at several discrete wave- lengths corresponding to the mercury lines in the 238-335 nm region. Therefore, we have decided to begin new work on this study in order to extend ...

Ozone Gas: Scientific Justification and Practical ...

06/04/2020· Small signal sensor response was less than 10 seconds, and a linear response was evident up to at least 25 ppm, though the manufacturer guarantees linear operation within specifications only to 20 ppm. Zero offset in clean air drifted between +/- , which equates to a random offset drift of approximately +/- ppm. During sampling, ozone generation was begun during each trace at the …
