UW Research

Environmental Analytical Research Laboratory (UWT EARL)



The purpose of EARL is to provide access to instrumentation, equipment, and training that can assist members of the University of Washington Tacoma and its surrounding community in their environmental research and general analytical needs. UWT SAM Division invites environmental scientists, students and researchers from neighboring higher education institutions as well as from industry and the community in general to inquire about the analytical instrumentation we have in our laboratories that can assist in their work, teaching or research projects for minimal cost.


Instruments are available for use typically on a cost per hour of use basis. We will provide proper training prior to using the instrumentation as well as access to work areas while you are performing your analyses.  Please do not hesitate to contact us at SAMEARL@uw.edu if you are interested in a particular analytical method or instrumentation.

Type: Equipment/Services

The instrumentation available for organic analyses are High-Performance Liquid Chromatograph (HPLC), Gas Chromatograph (GC), and Gas Chromatograph-Mass Spectrometer (GCMS). The instrumentation available for metals analyses are Microwave Digestion, Atomic Absorption Spectrometer, and Induced Coupled Plasma-Mass Spectrometer (ICPMS). For compound characterization we have available a Fourier Transform Infrared Spectrometer (FTIR), Nuclear Magnetic Resonance Spectroscopy (NMR), Ultra Violet-Visible Spectrometer (UV-Vis), and Particle Size Analyzer. In addition there is a Nutrient Analyzer for nutrient analyses.
