确定基于过滤器的气溶胶样品的累积质量是许多形式的科学研究和空气质量监管监测的基础。然而，空气采样过滤器的重量分析是繁琐的，耗时的，并且容易出现人为错误。这项工作描述了一个自动化的空气分析设备（AIRLIFT）的高通量重量质量和光学黑碳测量的过滤器为基础的气溶胶样品的发展。AIRLIFT由一个密封的环境外壳、一个6轴关节机械臂、一个可编程控制系统、一个过滤器称重装置和一个通过光衰减测定气溶胶炭黑的光学系统组成。该系统主动监测微量天平稳定性和测试箱相对湿度。数字成像和QR码扫描支持样品跟踪和数据记录。发现温度和湿度控制以及重量稳定性的性能指标符合或超过美国环境保护局规定的最低要求。AIRLIFT每天能够分析约260个过滤器，同时将所需的人员时间减少约4倍。
The determination of accumulated mass on filter-based aerosol samples is the basis for many forms of scientific research and regulatory monitoring of air quality. However, gravimetric analysis of air sampling filters is tedious, time-intensive, and prone to human error. This work describes the development of an Automated Air Analysis Facility (AIRLIFT) for high-throughput gravimetric mass and optical black carbon measurements of filter-based aerosol samples. The AIRLIFT consists of a sealed environmental enclosure, a 6-axis articulating robotic arm, a programmable control system, a filter weighing apparatus, and an optical system for the determination of aerosol black carbon via light attenuation. The system actively monitors microbalance stability and chamber relative humidity. Digital imaging and QR code scanning support sample tracking and data logging. Performance metrics for temperature and humidity control and weight stability were found to meet or exceed minimum requirements set forth by the US Environmental Protection Agency. The AIRLIFT is capable of analyzing approximately 260 filters per day while reducing the required personnel time by a factor of ~4.
