Our Facilities

Luke placing a sample in a tool

The EHL/TOAC laboratories are at 4225 Roosevelt Ave NE, Seattle, WA 98105.

Operations are organized by functional purpose and to allow instrumental analyses without co-location of sample preparation. This is particularly important when working with low concentrations of analytes.

We have five class A general purpose hoods, two acid digestion hoods, and one for bio-hazardous material sample preparation.
