resolution paleoclimatology at the University of Maryland
As of Spring 2012, the
instrumentation described here a University of Maryland cost
center; we accept both collaborative and contract samples for
stable isotope analyses. Contact us
for analysis methods, rate quotes and turnaround times.
CoLaboratory. Our focus is development of
replicated, high resolution proxy records of tropical
and sea surface conditions using measurements on trees and
corals. In 2010 we established a new laboratory for
paleoclimatology in the Chemistry
Geology at the University
Maryland, expanding and complementing
existing stable isotope facilities of the Laboratories
Geochemistry. and the Stable
Laboratory. Additional space for offices,
meeting is adjacent. Design and construction was
overseen by UMD
Facilities Planning, Dept of Geology and the College of
Mathematical and Physical Sciences (now CMNS): Webb Smedley,
Mike Brown, Marian Dombroski, Isaac Daniel, Chito Flores,
Bustamente, Tony Brown.
Room 1216 supports four light stable isotope mass
and online sample preparation devices. This
multiple 230V/20A and 120V/10A circuits with isolated
uninterruptible backup power; house compressed air;
control; dedicated venting; and multiple safety features for
highly toxic compressed gases. Four Micromass/
Isoprimes, one with multicollector, are currently
peripherals for dual inlet and continuous flow measurement
and S isotopes on carbonates, organics and water
samples. For our
high resolution paleo work, one of these systems is
measurements on high temperature conversion CO or
CO2 from solid organics; another is optimized for high
carbonate-derived CO2 analysis on samples as small as 50ug.
Sartorius C2P microbalance in a dedicated alcove provides
repeatability on sample masses.

flow-sensor alarmed fume hoods with DI, natural gas,
service, vacuum and electricity; bench space for
preparation of paleoclimatic samples from a variety of
archives, three microcentrifuges, one rotary microtome, and
emergency shower and eyewash.

multipurpose space. Rm 1212 has 5 offices
with space for
faculty, staff and students, a multipurpose space with
projector and whiteboards for group meetings, and a
A single high speed internet connection
is switched to access IRMS computers for remote control and
analysis; a high density rackmount server provides

Backup is to an
offsite network attached storage device.
