Limonene 50ppb NOx 54ppb! Tuesday 22 April 2008

Lights on at 12:53

NOx ended up higher than desired.. 54ppb instead of 25!! The main problem was with the background NOx mostly composed of NO… I will replace the filters and see if we can get rid of this problem.. I suspect it also affect the VOC impurities in the bag because when I injected O3 to convert the NO more than a thousand particles per cc were formed in the bag..

~45 min after lights on cToF is measuring about 7.5 ugm-3…

A bit more than an hour of lights on

105 min after lights on

Lights off at 14:53

Post-exp complete O3 = 2350ppb
