Download the PDF version Determination of Volatile Organic Compounds in Air Anne Jurek Introduction Air pollution is a growing problem due to the global economy and industrial development in many countries. As a result, the analysis of ambient air is a growing field. The Environmental Protection Agency developed Method TO-15 in order to analyze air
Influence of the E Cigarette Emission Profile by the Ratio of Glycerol to Propylene Glycol in E Liquid Composition
Full PDF Version Download Influence of the E Cigarette Emission Profile by the Ratio of Glycerol to Propylene Glycol in E Liquid Composition ABSTRACT The use of electronic cigarettes (E-cig) is popular because of the perception that they are less addictive and safer compared to the traditional cigarettes. Nevertheless, there are still harmful effects associated
On-road tailpipe emission characteristics and ozone formation potentials of VOCs from gasoline, diesel and liquefied petroleum gas fueled vehicles
On-road tailpipe emission characteristics and ozone formation potentials of VOCs from gasoline, diesel and liquefied petroleum gas fueled vehicles Download PDF Version HIGHLIGHTS VOCs from various types of vehicles were investigated systematically with the PEMS. Aromatics and alkanes were the dominant VOC groups from in-use vehicle exhaust. Aromatics were the major contributors of the total
Nutech 3000 THC & NMHC Analyzer Application Note for Wastewater VOCs Testing in San Francisco
Background Introduction This application note is provided by Cambrian Innovation, the leading wastewater treatment solution provider in US. They built a plant to help Anchor Brewing, one of the oldest beer producer in US, to deal with their wastewater and make sure that after their treatment, the wastewater's NMHC concentration should be within allowable limit. Cambrian used our
Analysis of 117 VOCs Compounds by Using Nutech 8910 Preconcentrator System
Application Note: Analysis of 117 VOCs Compounds by Using Nutech 8910 Preconcentrator System 【Abstract】 By Using three stage cryogenic system + GC/MS technology (Full Scan and/or SIM) 117 VOC compounds (TO15 + PAMS + Aldehyde Compounds Mix by Linde) in air be analyzed to check the 8910 instrument performance. The results shows that in 0.1-10.0ppb range, the calibration,

Study of VOC and Photochemical Ozone Pollution in the Pearl River Delta Region
Study of VOC and Photochemical Ozone Pollution in the Pearl River Delta Region 1 INTRODUCTION 1.1 Background 1.1.1 The rapid economic development in the Pearl River Delta (PRD) Region including Hong Kong Special Administrative Region over the past decade has resulted in changes in the nature of air pollutants emitted from various activities in the region. There has
US EPA Method TO-15 VS US EPA Method TO-14A
US EPA Method TO-15 VS US EPA Method TO-14A Compendium Method TO-15 is significant in that it extends the Compendium Method TO-14A description for using canister-based sampling and gas chromatographic analysis in the following ways: • Compendium Method TO-15 incorporates a multisorbent/dry purge technique or equivalent (see Appendix A) for water management thereby addressing a more extensive set of
Releases of Fire-Derived Contaminants from Water Pipes Made of Polyvinyl Chloride Polymer
Abstract: In order to assess the human exposure risks from the release of contaminants from water pipes made of polyvinyl chloride (PVC), experiments were carried out by subjecting the PVC pipe material to burning and leaching conditions followed by analysis of the emission and leachate samples. The emissions of burning pipes were analyzed by both infrared spectrometry and gas
Storage Stability of 66 Volatile Organic Compounds (VOCs) in Silicon-Lined Air Canisters for 30 Days
Storage Stability of 66 Volatile Organic Compounds (VOCs) in Silicon-Lined Air Canisters for 30 Days Abstract The recoveries of 66 volatile organic compounds (VOCs) typically analyzed as part of the United States (U.S.) Environmental Protection Agency’s (EPA’s) Compendium Method TO-15, were evaluated for two commercially available silicon-lined (SL) air canisters. The VOC recoveries were determined both in dry
