What is it about?
The Multichannel Organics In situ enviRonmental Analyzer (MOIRA), which fits in the back seat and cargo area of a hybrid vehicle, is a new instrument developed by researchers from Washington University in Saint Louis (WashU) for measuring speciated volatile organic compounds (VOCs) in the air and mapping concentrations of air pollutants.

Why is it important?
MOIRA is a mobile gas chromatography-mass spectrometry (GC-MS) instrument which measures VOCs in the air continuously at 10-minute time intervals. It has been deployed in the lab and pilot field studies of indoor air in a single-family residence and outdoor air during a mobile deployment. This technology allows researchers to characterize the concentration of VOCs and helps them identify populations at most risk of VOC exposure.
Perspectives
The innovation of MOIRA includes the relatively low cost and small size with high mobility, and the ability to measure hundreds of compounds in real time. Future applications might include indoor, outdoor, and lab measurements to grasp the impacts of VOCs on air quality, public health, and climate.
