Whole-rock analysis (major and trace element)

Typical Use:

This instrument is chiefly used to determine the bulk major and trace element composition of rocks, soils, sediments, and minerals. Ten major and minor elements (Si,Al,Ti,Fe,Mn,Mg,Ca,Na,K,P) are determined as well as 28 trace elements (Ba,Bi,Ce,Cr,Cs,Cu,Dy,Ga,Hf,La,Mo,Nb,Nd,Ni,Pb,Rb,Sc,Sm,Sr,Ta,Th,Tl,U,V,Y,Yb,Zn,Zr), and the minimum concentrations of five volatile elements (As,Br,Cl,F,S).

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 The instrument is equipped with an attached He tank allowing the analysis of loose powder and liquid. Custom calibration for those uses will be required.

User Fees:

Please see the website for current fees:

Instrument Priorities:

Priority use is for undergraduate student projects and class demonstrations. Contract work and visitor prepared samples run on a "first come, first served" basis.

Remote Use:


Sample Preparation:

Samples can be submitted as rocks, chips, or powders and/or loose sediment. Normal precautions for shipping rock samples or vials and/or bags should be taken to ensure no loss or mixing from breakage.

Currently we accept samples as small as 0.5 gm, in near future we will accept samples as small as 0.1 gm.

Standard Collections/Lab Blanks:

We have an extensive collection of reference materials of all types for the geosciences. We will run reference materials as unknowns with no charge if we use pre-made in-house glass pellets.


The instrument is completely automated and runs 24/7. The OXSAS software package is used to calibrate the instrument and reduce data. Data are sent in Excell spreadsheets.

Educational Use:

Class demonstrations are available for undergraduates Undergraduate student research projects are invited Graduate student research projects are invited Tutorials and other educational materials related to the lab are available

Support provided by:

Acquisition and operation of the instrument is supported solely by Hamilton College.
