Instrument Type

WHOLE ROCK ANALYSIS - XRF X-ray Fluorescence

Spectro Analytical X-lab 2000 Energy Dispersive Polarization XRF


Whole-rock analysis (major and trace element)

Typical Use:

Bulk major and trace element analysis of geological materials using fused beads and/or pressed powder pellets.

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.

User Fees:

Contact Tom Fleming to discuss your project.

Instrument Priorities:

Priority use is for undergraduate student research projects, class demonstrations, and SCSU Earth Science faculty research.

Remote Use:

Instrument computer can be controlled or observed via the internet.

Sample Preparation:

Finely powdered rock, mineral, sediment, or soil. 0.3 gms of sample is required for analysis of fused glass disk that provides major elements and a limited number of trace elements. 4.0 gms of sample is required for analysis of pressed powder pellets which provides higher precision trace element concentrations.

Standard Collections/Lab Blanks:

The instrument is calibrated with wide a range of geological standards from USGS, GSJ, CRPG, NIST, etc. The primary focus of our calibrations is silicate-rich materials that include rocks, minerals, soils, and sediments. We have a more limited number of carbonate and coal standards. Interested users with special needs are welcome to provide their own standard materials to recalibrate the instrument.


Fully automated spectrometer with 20 position sample changer. X-LabPro software package accommodates a variety of analytical models including fundamental parameters (Turboquant), Lucas-Tooth and Price, extended Compton, Alpha coefficient correction.

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.
