MRI: Acquisition of Particle Counter and Sizer

马里伍德大学健康与人类服务学院的人体性能实验室计划购买一台格林顺序移动粒子测定仪和计数器(SMPS C)、格林1.109型光谱仪、Ecochem PAS2000CE和LQ1-DC。该设备对玛丽伍德大学人类行为实验室的研究至关重要，并将加强我们对与研究相关的学生教育的承诺。SMPS C提供高精度和高分辨率的颗粒计数，最高可达107个颗粒/立方米。它可以根据尺寸分布(1~100或5~350或10~1100 nm的分布分析)表征柴油机排气颗粒，获得准确的颗粒计数，并模拟颗粒团聚速率和比表面积。由于颗粒数量和/或表面积对毒性至关重要，因此需要准确的大小和计数。颗粒衰减与距离排放源的距离和时间的关系的表征是理解排放颗粒物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.
