The Beckman Coulter Foundation has tasked our clinic team to design and develop a low-cost air quality monitoring device. This monitoring instrument will sample ambient air and analyze the black carbon (BC) content, providing a relative measurement of the BC concentration. The collected data will form a historical record of BC concentration to identify pollutant trends. The final deliverable to Beckman Coulter will be a fully tested functioning device that is ready for outdoor deployment for further testing.
