Analytical Instrumentation

Atomic absorption spectrophotometer

Perkin Elmer AAnalyst 200 Atomic Absorption Spectrophotometer

Atomic absorption spectrophotometry provides accurate quantitative analyses for metals in water, sediments, soils, or rocks. (Samples are analyzed in solution form, so solid samples must be leached or dissolved prior to analysis.)

How it works

As shown in the schematic, atomic absorption units have four basic parts: interchangeable lamps that emit light with element-specific wavelengths, a sample aspirator, a flame or furnace apparatus for volatilizing the sample, and a photon detector. In order to analyze for any given element, a lamp that produces a wavelength of light that is absorbed by that element is chosen.

Sample solutions are aspirated into the flame. If any ions of the given element are present in the flame, they will absorb light produced by the lamp before it reaches the detector. The amount of light absorbed depends on the amount of the element present in the sample. Absorbance values for unknown samples are compared to calibration curves prepared by running known samples.

Broadband Seismometers

owns and operates six broadband seismometers, designed to record ground motion from local earthquakes as well as earthquakes across the globe.  The seismometers include five Nanometrics Meridian Compact Posthole Seismometers and one Streckeisen STS-2.5 seismometer paired with Quanterra Q330S+ digitizer.

Broadband seismometers measure ground motion across a broad range of frequencies, detecting not only earthquakes, but also storms, footsteps, loud noises, and even passing vehicles!  These instruments measure ground motion (as movement velocity) as small as micrometers per second, and in three dimensions.  Motion is recorded electronically as a suspended weight moves independently from the casing, passing a magnet through coiled wires, inducing an electrical current.  To collect meaningful information on ground motion, these broadband seismometers are buried in locations of geologic interest for periods of time ranging from months to several years.

Geometrics 24-channel Geode Seismic Acquisition System

This seismic acquisition system measures ground motion to image the upper 10s to 100s of meters of the subsurface.  

Students us Geode seismic system in class
Students us Geode seismic system during a geophysics lab

The Geode seismic acquisition system includes 24 sensitive geophones that measure ground motion at very high frequencies at evenly-spaced distances.  Signals recorded by this system are typically from a man-made source, such as a weight-drop or the impact of a sledgehammer on a metal plate.  Timing of this signal is precisely synchronized with all 24 geophones to create records of how energy is transmitted through the ground, and how it reflects off of subsurface interfaces.

Geometrics G-857 Magnetometer

This instrument measures tiny deviations in the strength of the magnetic field, which are induced by changes in geology or by remnants of human activities.

The G-857 is a proton procession magnetometer, which measures magnetic fields to a sensitivity of tenths of a nanoTesla.  The sensor is filled with a fluid containing hydrogen atoms.  A strong magnetic field is created around the fluid, causing the protons of the hydrogen atoms to align within the field.  When the artificial magnetic field is released, the protons realign with the natural ambient magnetic field, creating an electrical current that is recorded by the instrument and converted to magnetic field strength.  By making measurements like this in many locations, we can create a map showing how the magnetic field varies spatially.  This can reveal changes in subsurface geology, buried objects containing small amounts of ferrous material, or even disturbed soils.

Inductively coupled plasma — mass spectrometer

Varian/Bruker 820-MS and Agilent HP4500

Inductively coupled plasma mass spectrometers (ICP-MS) measure the concentrations of trace and major elements in liquid or solid samples. The Varian 820-MS ICP-MS is set up to process data from solutions using the Cetac ASX-520 autosampler or solids using the New Wave UP 213nm laser ablation system. This laser ablation system allows researchers to get pinpoint, in situ data from solid samples like rocks, glass, and crystals. Both the Varian and Argilent instruments housed in this lab are quadrupole ICP-MS systems, so researchers can measure the majority of the periodic table in just seconds.

How it works

A beam of high-energy electrons is produced in the electron gun at the top of the column by applying high voltage to a tungsten filament and nearby anode. This beam is accelerated past the anode into the column, where it is condensed and aligned by a series of electromagnetic lenses and coils within the column. This focused beam continuously rasters back and forth across the sample. Interactions between the electron beam and the sample result in different types of emissions that are measured by a series of detectors located within the sample chamber. The types of emissions that are measured are: secondary electrons, backscattered electrons, x-rays, and cathode luminescence. X-ray data is sent to the x-ray system, where it is translated into elemental plots. The other three detectors are connected to a monitor where the signal produces a clear image of the sample. Secondary electron imaging provides good three-dimensional topographic views of the sample. Backscattered electron images show less-defined topography but clearly display differences in elemental compositions because higher-atomic-number elements appear brighter. Cathode luminescence imaging highlights chemical variations within individual grains due to trace element variations and zoning.

Instrument statistics

’s EDS system is run by Inca software. The detector has a beryllium window. Quantitative analyses are performed at 20 kV using a 25 mm working distance, 35 percent dead time, and are collected for 200 seconds of live time.

Stable isotope mass spectrometry

Delta Plus Advantage Stable Isotope Mass Spectrometer and Costech Elemental Analyzer

Funded by grant EAR-0216179 from the National Science Foundation

This system measures isotope ratios of C, O, and N from geological and biological samples.

Student using stable isotope mass spectrometer in lab.
Student using stable isotope mass spectrometer in lab.

How it works

Oxygen, carbon, or nitrogen must be separated from samples by some chemical method (such as combustion, dissolution in acids, or fusing with a laser in the presence of an oxidizer). Gases are then purified in a vacuum line (glass trellis-work in picture) or within the elemental analyzer. The purified gases are then introduced into the mass spectrometer, either by using the dual-inlet system or continuous flow mode, where they are bombarded by electrons and ionized. The ions travel down a flight tube and are separated according to mass by an electromagnet. The ions are then detected in Faraday cups at the end of the flight tube. The isotope ratio is calculated from the charge of the ions at the end of the flight tube. See Finnigan's brochure for instrument and analytical statistics.

Although the differences in mass between the isotopes of the light gases are small (~11 percent between 16O and 18O), the isotope ratio is very sensitive to geological processes. Stable isotopes are commonly used in studies to determine paleoclimate, water-rock interaction, and metamorphic temperatures in rocks, and trophic level and paleodiet in fossils.

Research projects

The lab is used for class projects in geology and other departments (e.g., ENST 100 Earth and Environmental Processes, FSEM 124 Forensic Geology, GEOL 310 Economic Geology, GEOL 415 Marine Geology, GEOL 411 Isotope Geology, BIOL 476 Biodiversity and Ecosystem Ecology). Class projects have investigated plant physiology, lake sediments near Hamilton, N.Y., the origin of Pb-Zn ore deposits, and adulteration of maple syrup. Many students have used the lab for independent study projects and senior theses, and several have presented their projects at regional and national meetings.

X-ray diffractometer

Philips PW3040 X-ray Diffractometer with X'Pert Software

Purchased with a grant from the National Science Foundation
X-ray diffraction is used to determine the identity of crystalline solids based on their atomic structure.

Student using x-ray diffractometer in lab
Student using x-ray diffractometer in lab.

’s system uses Cu Kα radiation that has a wavelength of 1.54Å. Analyses are commonly run using a 40kV 45mA x-ray tube voltage, a 0.04° soller slit, 1° divergence and antiscatter slits, and a 1/2° (for powder) or 1/4° (for clays) receiving slit.

How it works

During x-ray diffraction analysis, x-ray beams are reflected off the parallel atomic layers within a mineral over a range of diffraction angles. Because the x-ray beam has a specific wavelength, for any given 'd-spacing' (distance between adjacent atomic planes) there are only specific angles at which the exiting rays will be 'in phase' and therefore rays will be picked up by the detector producing a peak on the 'diffractogram.' Like a human fingerprint, every mineral has its own distinct set of diffraction peaks that can be used to identify it.

Paleontology Research Collection

The Earth & Environmental Geosciences Department at has an extensive fossil collection, largely made up of identified invertebrate fossils from the Middle Devonian Hamilton Group. 

Middle Devonian rocks in New York State are largely marine and represent shallow coastal environments to the east and deeper basinal environments to the west. Most of the fossils at are from within a 30 km radius of Hamilton, NY, and represent a shallow midshelf fauna rich in brachiopods and bivalves. High sediment influx and variable salinity produced conditions that were distinctly different from the normal marine to anoxic environments in the western part of the state. 

has about 5000 lots (185 drawers) of identified Hamilton Group fossils. These are from the upper Marcellus, Skaneateles, Ludlowville, and Moscow formations. In addition, there are 750 lots of western New York Hamilton Group fossils, which include many corals, 500 lots of Lower and Upper Devonian fossils, and 200 lots of eurypterids from the Bertie Waterlime. 

The Robert M. Linsley Collections at comprise an impressive set of identified Tertiary and modern molluscs with around 4000 lots of gastropods and 1300 lots of bivalves. Part of the modern collections are from Albert Bickmore, who collected in the Netherlands East Indies and southwest Pacific in 1865. 

In addition to the teaching collection, there are 250 drawers of non-Devonian invertebrate and plant fossils. 160 drawers are an identified and diverse invertebrate collection spanning the Phanerozoic, 60 drawers are Cenozoic marine molluscs from Florida, and 30 drawers contain Upper Paleozoic and Cenozoic plant fossils.
