A simple and precise methodology to determine particulate matter mass in atmospheric filters

In the past decades, particulate matter (PM) measurements have been used extensively in atmospheric sciences, as it allows studying the evolution of tracers for different atmospheric processes and the effects of atmospheric pollution on human health. However, measuring PM mass requires a constant co...

However, measuring PM mass requires a constant control of the laboratory conditions due to its capacity to absorb humidity.
