Particulate mass was assessed by pre- and postweighing of the filters in an environmentally controlled weighing room using a microbalance at 1 μg accuracy.
Challenges associated with gravimetric sampling include the need for careful filter handling and an expensive analytical balance for weighing the filters that is maintained within a temperature, and humidity, controlled weighing lab.
