Increasing interest in gas emissions from animal agriculture operations may lead to development of new mitigation practices that will need to be field tested. A proposed protocol recommends collecting air samples over a 24-hour period. This report describes the design, performance and results from initial tests of a portable system for filling 50 L air sample bags over 24-hour sampling periods. Two bag filling schedules were tested, filling a sample bag 4 seconds every minute and filling the bag for 4 minutes every hour. The bag sample concentrations were compared to semi-continuous sampling system concentrations.
