MRI: Acquisition of Particle Counter and Sizer

CBET-0723010 Rundell 玛丽伍德大学健康与人类服务学院的人类行为实验室计划购买GRIMM顺序迁移率粒度仪和计数器（SMPS +C）、GRIMM 1.109型光谱仪、EcoChem PAS 2000 CE和LQ 1-DC。该设备是必不可少的玛丽伍德大学人类绩效实验室的研究，并将加强我们对研究相关的学生教育的承诺。SMPS +C可提供高精度和高分辨率的颗粒计数，最高可达107个颗粒/cm 3。它可以根据粒度分布（分布分析在1至100或5至350或10至1100 nm之间）表征柴油机排气颗粒，获得准确的颗粒计数，并对颗粒团聚率和表面积进行建模。由于颗粒数量和/或表面积对毒性至关重要，因此需要准确的尺寸和计数。与距离和时间有关的颗粒衰变特性是理解排放颗粒毒理学的关键组成部分。

CBET-0723010 Rundell The Human Performance Laboratory in the College of Health and Human Services at Marywood University plans to acquire a GRIMM Sequential Mobility Particle Sizer and Counter (SMPS +C), GRIMM model 1.109 Spectrometer, EcoChem PAS 2000 CE and LQ1-DC. This equipment is essential to the research of the Marywood University Human Performance Laboratory and will enhance our commitment to research-related student education. The SMPS +C provides high accuracy and resolution of particles with counts up to 107 particles/cm3. It can characterize diesel exhaust particles according to size distribution (distribution analysis between 1 to 100 or 5 to 350 or 10 to 1100 nm), obtains accurate particle counts, and model particle agglomeration rates and surface area. Since particle number and/or surface area are critical to toxicity, accurate sizing and counts are needed. Characterization of particle decay in relation to distance and time from emission source is a critical component to understanding emission particle toxicology.
