Abstract: In a material sample separation and collection system, a sample is obtained by airflow separation. The system and attendant methods collect a complete sample over a defined period of time by modulating one or more pressure balancing valves, thus allowing for a variable flow rate of materials through the system even while the fan or other source of airflow operates at constant speed. The sampling rate, which is based on how quickly or slowly materials enter and pass through the system and into a collection vessel, is automatically modulated in real time based on sensor data.
