This study evaluated a novel robotic direct reading method that used a real-time location system to measure the spatial-concentration distribution of volatile organic compounds (VOCs) in a chemistry laboratory. The CEMWIP II is a custom-made sensor that measures VOCs, temperature, humidity, and location, sending data wirelessly in real time to a remote location for display and storage. In this study, the CEMWIP II device was mounted on a robotic platform to create a CEMWIP II-mobile platform. The autonomous mobile platform was released from a corner of the room and allowed to travel randomly along an open floor with the goal of characterizing the spatial distribution of VOCs and identifying their sources in the laboratory. The experiment consisted of 12 runs made of permutations of four corner release sites and four beaker locations, with two beakers containing water and two containing the solvent acetone. The autonomous mobile platform was tasked with locating the two beakers of acetone. The sensor had a detection limit of 100 ppb and the confidence of detecting a source within a 1.46 m² area was p = 0.0005 by ANOVA. The CEMWIP II-mobile platform was able to measure the spatial distribution of VOCs within a laboratory that were associated with open solvent containers.

这项研究评估了一种新颖的机器人直接读取方法，该方法使用实时定位系统来测量化学实验室中挥发性有机化合物（VOC）的空间浓度分布。CEMWIP II是一种定制传感器，可测量VOC，温度，湿度和位置，将数据实时无线发送到远程位置进行显示和存储。在这项研究中，CEMWIP II设备安装在机器人平台上，以创建CEMWIP II移动平台。自主移动平台从房间的一角释放出来，并允许其在开放的地板上随机移动，目的是表征VOC的空间分布并在实验室中确定其来源。该实验由12个运行组成，这些运行由四个角释放位置和四个烧杯位置的排列组成，装有两个装有水的烧杯和两个装有丙酮的溶剂。自主移动平台的任务是找到两个丙酮烧杯。该传感器的检测极限为100 ppb，在1.46 m以内检测到源的置信度通过ANOVA，²面积为p ＝ 0.0005。CEMWIP II移动平台能够测量实验室中与开放式溶剂容器相关的VOC的空间分布。
