Instrument Type

ELECTRON MICROBEAM - EDS energy dispersive spectrometer ELECTRON MICROBEAM - EMPA electron microprobe; wavelength dispersive spectrometers




Typical Use:

Meteoritics, Moon, Mars and Asteroidal samples
Terrestrial mantle and volcanics min/pet,
compositional mapping,
sedimentary rock geochem.,
characterization of samples for laser Ar-Ar age dating,
materials characterization both academic and commercial

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 design and do the work yourself Training Session (short course) is offered

User Fees:

Lab is a self supporting entity so that fee structure is designed to meet operating costs.
ALL users pay hourly/daily user fees and bulk time purchases can be negotiated.
It is preferred that users perform their own data collecting after training and orientation, but for small projects, assistance can be arranged.

Instrument Priorities:

1.Funded research from Rutgers and elsewhere
2.Student projects
3.Reconnaisance studies to define projects
4.Outside Users

Remote Use:

This is currently under development for simple data acquisition and processing. Issues for detailed petrologically controlled studies caused by time delays involved in imaging are being considered to determine the extent to which remote analysis is viable.

Sample Preparation:

Users are expected to provide fully prepared (polished) samples for microanalysis. We will provide conductive coating (usually C) if needed and this is impractical for the user at their home institution.

Standard Collections/Lab Blanks:

Microanalytical Standards are based on the NMNH standard suite characterized by Gene Jarosewich with many additions from other sources.
Imaging standards are available.


Instrument operates on Solaris based system with PC interface that provides JEOL analytical protocols as well as StarOffice package. The current "Probe for Windows" package will be implemented in the near future
PC based support computers are available with Image Editing, data processing software (Probe for Windows5.4, Grapher, Surfer, Adobe CS2 package including Photoshop, Acrobat etc), as well as MS-Office package including Excel,Word and Powerpoint. Web access is available

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
