Abstract

<p>Goals:<br/> Measure the background concentrations created by exposing the bag to OH. Sample ISOPN pillow bags. Interested mainly in:<br/> -what signals do the instruments see with no added VOC.<br/> -which instruments observe signal from the ISOPN, and is their response linear to different ISOPN concentrations.</p> <p>Summary:<br/> Today we successfully ran a blank experiment (H2O2 added, no added VOC) in the high NOx bag. Instruments took turns coming off the blank experiment to sample pillow bag standards of the 4-OH, 3-nitrate isoprene hydroxynitrate provided by the Cohen and Shepson groups. The Cohen group bag was 13 ppb and the 3 Shepson bags were 47 ppt, 103 ppt, and 283 ppt.</p> <p>Organization: 2014 FIXCIT Study<br/> Lab Affiliation: California Institute of Technology<br/> Chamber: Seinfeld chambers</p> <p>Experiment Category: Blank/Control<br/> Oxidant: Hydroxyl radical<br/> Reactants: 4-hydroxy-3-nitrooxy ISOPN, hydrogen peroxide<br/> Reaction Type: Photooxidation<br/> Relative Humidity: 5<br/> Temperature: 24-27<br/> Pressure: 750</p>
