Our Facilities

The EHL/TOAC laboratories are in the UW Magnuson Health Sciences Center, F-Wing, 4th floor.

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.
