Popularity of electronic cigarettes (ECIGs) has increased tremendously among young people, in part due to flavoring additives in ECIG liquids. Pyrazines are an important class of these additives, and their presence in tobacco cigarettes has...
Size-Selective Sampling Performance of Six Low-Volume "Total" Suspended Particulate (TSP) Inlets [0.03%]
六种低体积"TSP"采样器入口的选择性大小采样性能分析

Conventional methods to measure the metallic content of particles by size are time consuming and expensive, requiring collection of particles with a cascade impactor and subsequent metals analysis by inductively coupled plasma mass spectrom...
Evaluation of the Alphasense Optical Particle Counter (OPC-N2) and the Grimm Portable Aerosol Spectrometer (PAS-1.108) [0.03%]
阿尔法感官光学颗粒物计数器（OPC-N2）和格林便携式气溶胶光谱仪（PAS-1.108）的评估结果

Porous polyurethane foam was evaluated to replace the eight nylon meshes used as a substrate to collect nanoparticles in the Nanoparticle Respiratory Deposition (NRD) sampler. Cylindrical (25-mm diameter by 40-mm deep) foam with 110 pores p...
Inter-comparison of Low-cost Sensors for Measuring the Mass Concentration of Occupational Aerosols [0.03%]
低成本传感器测量职业气溶胶质量浓度的相互比较研究
Sinan Sousan,Kirsten Koehler,Geb Thomas et al.
Sinan Sousan et al.
Low-cost sensors are effective for measuring the mass concentration of ambient aerosols and secondhand smoke in homes, but their use at concentrations relevant to occupational settings has not been demonstrated. We measured the concentratio...
