Instrument Type

ELECTRON MICROBEAM - EMPA electron microprobe; wavelength dispersive spectrometers

JEOL 733



Typical Use:

Spot analyses of inorganic solids, x-ray mapping, secondary and backscattered imaging.

Conditions for Use:

Submitted samples will be analyzed on a contract basis (i.e. lab personnel will do the work).
Visitors are invited to work in the lab to work with lab personnel.
Visitors are invited to work in the lab to design and do the work yourself.
Training Session (short course) is offered.

User Fees:

$39/hr for time charged to state or federal grants,
$150/hr for business.

Instrument Priorities:

UW students have first priority, all others are scheduled as the calendar permits.

Remote Use:

No, it is not possible to remotely operate the probe at this time.

Sample Preparation:

All samples for WDS analysis must be polished and carbon coated. Mounting and polishing can be done here (no extra charge unless this is a lot of samples), or at a commercial lab. Carbon coating is at no charge.

Standard Collections/Lab Blanks:

We have over 100 well characterized mineral and glass standards that have been used routinely in this lab.


The microprobe uses the GELLER dQant and dSspec automation system. We also have two digital imaging systems, the GELLER dPict and GATAN DigitalMicrograph.

Educational Use:

Class demonstrations are available for undergraduates.
Class demonstrations are available for K-12.
Undergraduate student research projects are invited.
Graduate student research projects are invited.
