Laboratory for Environmental Analysis of Forests (LEAF)

The LEAF offers 2,200 square feet of laboratory space dedicated to the study of carbon, nutrient, and trace element movement and cycling through plants, soil and water in terrestrial ecosystems, and into adjacent aquatic ecosystems. Analytical services are typically provided on a fee per sample basis. The LEAF provides Michigan Tech investigators (1) expert advice on sampling and analytic techniques for elements in water, soil, and plant tissues, (2) supervision of students preparing samples for analysis, (3) space and equipment to perform sample grinding, extractions, filtering, and microwave digestion, and (4) analytic instrumentation for quantitative analysis of elemental composition of liquids and solids and isotopes of C and N in liquids, solids, and gases.
