The Department of Biomedical Materials
Science at the University of Mississippi
Medical Center (UMMC) was formed in July
2004 but has existed as a division within
another department for approximately 35
years. As a part of the academic program
of the School of Graduate Studies in the
Health Sciences and the School of
Dentistry, efforts are dedicated to research,
development, and characterization of
materials, and the interfacial and biological
phenomena that govern the outcome of
biomedical implants and devices.
In light of the fact that the equipment
available in our laboratories represents the
state of the art in material testing and
characterization, and requests from a
variety of industries and other universities
for access to this equipment, the
department has formalized a shared
equipment facility.
This facility provides access to equipment
used to perform materials processing,
characterization, and certification. These
services are now available to users within
and outside the academic community on a
fee-for-service basis.
Users may become trained in the use of the
equipment and be allowed independent

The lack of high-voltage ion extraction
lenses results in lower on-peak
background levels and lower
equivalent concentrations leading to
accurate quantitative measurements
at ultra trace levels.
Elan DRC II allows accurate
determinations at the ppb levels for
several important elements.
The laser ablation system can
volatilize solid samples into a gas
carrier stream that can then be fed to
the ICP-MS for compositional analysis.
The CETAC LSX-213 delivers high
intensity 213 nm, 5 nanosecond laser
pulses at rates of 1-20 Hz.
The homogeneous flat top energy profile
of the laser produces aperture spot sizes

maintaining a constant energy density.
The laser output energy is fully
adjustable to produce as much, or as
little ablation necessary to analyze
virtually any solid sample - ideal for
geological, forensic industrial and
biological samples.
For analysis, you can easily set
precise points for a single point
analysis, multi-point analysis, line
scan analysis, area scan analysis,
area raster analysis, depth profiling, or
analyzing an arbitrary pattern.
