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

Robert W Vanderpool et al.
Several low-volume inlets (flow rates ≤16.7 liters per minute (Lpm)) are commercially available as components of low-cost, portable ambient particulate matter samplers. Because the inlets themselves do not contain internal fractionators, t...

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

We compared the performance of a low-cost (∼$500), compact optical particle counter (OPC, OPC-N2, Alphasense) to another OPC (PAS-1.108, Grimm Technologies) and reference instruments. We measured the detection efficiency of the OPCs by siz...
Porous Polyurethane Foam for Use as a Particle Collection Substrate in a Nanoparticle Respiratory Deposition Sampler [0.03%]

Levi W D Mines et al.
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 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...
Production of neutral molecular clusters by controlled neutralization of mobility standards [0.03%]
通过控制_mobility_标准的中和来产生中性分子团簇

G Steiner et al.
Measuring aerosols and molecular clusters below the 3 nm size limit is essential to increase our understanding of new particle formation. Instruments for the detection of sub-3 nm aerosols and clusters exist and need to be carefully calibra...
Transport phenomena governing nicotine emissions from electronic cigarettes: model formulation and experimental investigation [0.03%]
电子烟尼古丁排放的传输现象：模型制定与实验调查
