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.

离心颗粒质量分析仪（CPMA）是一种测量气溶胶中纳米颗粒质量的仪器，范围为0.2阿托克至1，000毫微微克。这种仪器对于测量纳米颗粒的特性是必要的，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：测量飞机微粒排放量并制定新的飞机微粒排放标准，确定油砂开采活动微粒排放量的排放系数，测量火炬烟囱的烟尘排放量，以及测量使用乙醇的汽油直喷发动机的微粒排放量。这些信息将有助于利益相关者和政策制定者就这些排放的风险以及如何减少其排放或影响做出明智的决定。
