SBIR Phase I: A Compact, Single Particle Black Carbon Spectrometer For Small, Airborne Platforms

该小型企业创新研究(SBIR)研究项目将开发一种轻型、低功耗、快速响应、高灵敏度的仪器，用于测量地面和机载应用中的黑碳气溶胶(BCA)的质量浓度。紧凑型单粒子烟尘光度计(CSP2)将利用激光诱导白炽光与光散射相结合的方法来计算大气气溶胶中黑碳(BC)的质量，以及与BC混合或不混合的颗粒直径，并估计BC的相对质量分数。第一阶段的目标是一个实验室原型，以展示新仪器设计的灵敏度、稳定性和准确性。该仪器可用于环境气溶胶黑碳的环境测量，用于气候和健康研究，以及用于黑碳排放研究的来源采样。

This Small Business Innovation Research (SBIR) research project will develop a lightweight, low power, fast response, high sensitivity instrument for measuring the mass concentration of black carbon aerosols (BCA) in ground based and airborne applications. The compact, single particle soot photometer (CSP2) will employ laser induced incandescence, coupled with light scattering to derive the mass of black carbon (BC) in atmospheric aerosols, the diameter of particles, mixed or unmixed with BC and estimate the relative mass fraction of BC. The Phase I objective is a laboratory prototype that demonstrates the sensitivity, stability, and accuracy of the new instrument design. This instrumentation has application to ambient measurements of aerosol black carbon for climate and health research as well as source sampling for emission studies of black carbon.
