Facilities, Equipment, and Other Resources
Sediment samples from the Finger Lakes being analyzed for total
mercury using the FLI’s Milestone DMA-80 analytical system.
There is a ~700 square foot laboratory in the Finger Lakes Institute that houses equipment that is used for research and education purposes. For field investigations, the FLI has a YSI hand-held physical-chemical meter (YSI-556), a Smith Root Backpack Electrofisher combo unit, an Ekman dredge, secchi disks, plankton nets, and numerous dip nets. Other field instruments deployed for the Finger Lakes Stream Monitoring Network include Vernier Labquest units with dissolved oxygen and temperature probes, LaMotte nitrate and chloride kits, and Oakton pH probes.
The FLI also has ten Zeiss compound microscopes and two dissecting microscopes for identification of biological organisms such as phytoplankton, periphyton, macroinvertebrates, and macrophytes.
For laboratory analysis of total mercury, the FLI houses a Milestone Direct Mercury Analyzer (DMA 80) that is used for analysis of solid phase samples such as biological tissue and sediments. This instrument combines the techniques of thermal decomposition, catalytic conversion, amalgamation, and atomic absorption spectrophotometry for analysis. Limits of quantitation for liquid and solid phase samples based on blank sample boat analyses were determined to be 0.02 ng and 0.01 ng, respectively.

In 2016, the FLI also acquired a Brooks Rand Instruments MERX-M automated methyl mercury analyzer. This instrument enables measurements of solid samples with ultra low methylmercury concentrations, such as benthic invertebrates and zooplankton. Mercury is detected on a Brooks Rand Model III cold vapor atomic fluorescence spectrophotometer, with an instrument detection limit of <0.002 ng/L.
The FLI lab also has an analytical balance and drying oven for sample preparation.
