At the Harvard School of Engineering and Applied Sciences, the Sunderland lab is conducting analysis of environmental samples. Specifically, they are analyzing trace metals and PFAS in water, soil, sediment and biological tissues. Their laboratory is made up of different instruments to aid in their research and analysis.

“Our research goal is to better understand how chemicals released by human activity interact with natural ecosystems and affect living systems. A main innovation of our group’s work is to quantitatively analyze the entire exposure pathway for aquatic pollutants to identify key processes that have a large influence on their accumulation in biota. Our research approach combines environmental measurements with statistical and mechanistic simulation models to project chemical levels over space and time. This integrated approach allows us to better understand how global change (both chemical releases and climate change) will affect human and ecological health risks associated with environmental toxicants.”

They make use of Organomation’s 24 position N-EVAP nitrogen blowdown evaporator to help in their analysis. Our nitrogen evaporators utilize adjustable nitrogen blowdown technology allowing for full control of nitrogen flow to samples, with no wasted nitrogen gas. We combine this technology with uniform heat applied efficiently through either water or dry baths. This technique saves labs money by simultaneously maximizing solvent evaporation volume and rate.
