Article Title: Oxidation of gaseous elemental mercury in the presence of secondary organic aerosols
Article Snippet: Gaseous elemental mercury (GEM; Hg(g)) was oxidized by ozone and secondary hydroxyl radicals generated by the chemistry associated with the formation of secondary organic aerosols.. The reaction was investigated in a 9-m3 Teflon batch reactor.. The losses of GEM in ozone-only experiments compared well with numerical model predictions based on published reaction rates, and a second order rate analysis gave a reaction rate of (7.4 0.5) 10 19 cm3 molecules 1 s 1, which was statistically indistinct from recent publications.

Article Title: Reduction of biogenic VOC sampling losses from ozone via trans-2-butene addition.
Article Snippet: Thecontinuousadditionof trans-2-butenetoaircontainingozonereactive volatile and semivolatile organic compounds prior to sampling on Tenax-TA adsorbent was found to be an effective means of removing ozone and reducing analyte losses of ozone reactive biogenic volatile organic compounds (BVOCs).. To allow sufficient time for ozone scavenging to occur, the reacting mixture is passed through a heated (40 °C) coil of Sulfinert (Restek Corp., Bellefonte, PA) treated stainless steel tubing.. The method was evaluated using a test mixture consisting of terpenes, terpenoid alcohols, and sesquiterpenes at part per trillion (pptv) levels in air in the presence of 100 parts per billion (ppbv) of ozone.

Article Title: Evaluation of sample recovery of malodorous livestock gases from air sampling bags, solid-phase microextraction fibers, Tenax TA sorbent tubes, and sampling canisters.
Article Snippet: .. Pure air was generated by zero air generator (model 737, AADCO, Village of Cleves, OH). ..

Sampling:

Article Title: Development of an In Situ Thermal Desorption Gas Chromatography Instrument for Quantifying Atmospheric Semi-Volatile Organic Compounds
Article Snippet: .. Then, particle and hydrocarbon free air from a zero air generator (model 737, AADCO, Cleves, OH, USA) was drawn at 10 L/min through the F-CTD for either 30 or 90 min, to simulate normal ambient sampling (either 30 or 90 min). ..

Produced:

Article Title: Use of a heated graphite scrubber as a means of reducing interferences in UV-absorbance measurements of atmospheric ozone
Article Snippet: .. Dry air (< 2 % relative humidity) was produced using a zero air generator (Aadco, Model 737) or from cylinders of zero grade air. ..

Purification:

Article Title: Secondary Organic Aerosol Formation and Organic Nitrate Yield from NO 3 Oxidation of Biogenic Hydrocarbons
Article Snippet: .. Prior to each experiment, the chamber was cleaned using a pulse of ppm-level ozone (20 ppm for ~ 5 minutes) from an electrical discharge ozone generator (Welsbach, Inc.), using pure oxygen to avoid the generation of NOx, followed by 20-30 hours of purified air at a flow of 40 lpm from a zero air generator (Model 737, Aadco Instruments) through HEPA filters (Pall Life Sciences model 12144). ..
