Centrifugal Particle Mass Analyzer

离心式粒子质量分析仪(CPMA)是一种测量气溶胶中纳米粒子质量的仪器，测量范围为0.2微克到1000微克。该仪器对于测量纳米粒子的性质是必要的，这样我们就可以了解它们对人类健康、空气质量和气候的影响。CPMA将用于：测量飞机颗粒物排放和开发新的飞机颗粒物排放标准，确定油砂开采活动颗粒物排放的排放系数，测量火炬烟囱的烟尘排放，以及测量汽油定向喷射发动机使用乙醇的颗粒物排放。这些信息将帮助利益攸关方和政策制定者就这些排放的风险以及可以采取哪些措施减少其排放或影响作出明智的决定。

The Centrifugal Particle Mass Analyzer (CPMA) is an instrument that measures the mass of nanoparticles in an aerosol with a range of 0.2 attograms to 1,000 femtograms. This instrument is necessary for measuring the properties of nanoparticles so that we can understand their effect on human health, air quality, and climate. The CPMA will be used to: measure particle emissions from aircraft and develop a new aircraft particle emission standard, determine the emission factors of particulate emissions from oil sands mining activities, measure the soot emissions from flare stacks, and measure particle emissions from gasoline direction injection engines operating on ethanol. This information will help stakeholders and policy-makers make informed decisions about the risks of these emissions and what can be done to reduce their emission or effect.
