Laboratory at Albion College
Dedicated
April 20th, 2001
The Dow Analytical Science Lab is an interdisciplinary
analytical laboratory serving the natural sciences and mathematics
departments at Albion College. The instrumentation is used in both
faculty/student research project and undergraduate coursework.
The instrumentation found in the lab is listed below, along with a brief
description of their use.
 |
Instrument:
JEOL 400 MHz Eclipse Multi-Probe Nuclear Magnetic Resonance Spectrometer (NMR)
Applications:
Technique is similar to MRI.
Provides detailed structural information for the identification of
organic compounds. |
| Instrument:
JY 38 S Inductively coupled plasma/atomic emission spectrometer
Applications:
Determination of concentrations of cations, including metals, at low levels
in environmental and other kinds of samples
|
 |
 |
Instrument:
Photon Technology Fluorescence Spectrometer
(Time-Resolved and Steady State)
Applications:
Laser excites sample and then the analyte molecules fluoresce at
specific wavelengths of light.
Useful
technique for the analysis of biomolecules and organics.
Both steady-state (QM4) and time-resolved
(LaserStrobe) analyses are available. |
| Instrument:
Micrometric SediGraph 5100 Particle Analyzer
Applications:
Measures the size distribution of small particles in environmental and
other samples.
|
 |
 |
Instrument:
Waters 2690 separations module; Waters 996 photodiode array detector;
Micromass ZMD 4000 High-Pressure Liquid Chromatograph/Mass Spectrometer (HPLC
and LC-MS)
Applications:
Allows for the separation and analysis of organic liquids
and aqueous solutions.
The
mass spectrometer is a detector that allows the exact determination of the
compound(s) present.
|
| Instrument:
CEM Mars 5 Microwave Digester
Applications:
Rapid preparation of samples for analysis by instrumental
methods
|
 |
 |
Instrument:
Varian Cary 300 Bio Ultra-violet/visible spectrometer (UV/vis)
Applications:
Samples absorb UV/Vis light.
The wavelength of light that is absorbed is characteristic of the
molecule or ion in the sample.
The
intensity of the light absorbed is proportional to the amount of analyte
present. |
| Instrument:
Applied Biosystems Gene Amp PCR 9700 DNA Sequencer
Applications:
Allows
for the automatic analysis of gene sequences.
|
 |
 |
Instrument:
Dionex DX 500 Ion Chromatograph
with Autosampler
Applications:
Identification and quantification of anions in solution,
such as environmental samples. |
| Instrument:
Agilent 6890/5973 Gas Chromatograph-Mass Spectrometer (GC-MS)
with Headspace analyzer
Applications:
Identification and quantification of most organic compounds in
research, environmental, and other samples.
|
 |
 |
Instrument:
Rigaku Multiflex X-ray diffractometer
Applications:
Samples absorb x-ray radiation which is reemiteed by sample
as wavelengths characteristic of its elements.
X-ray emission
intensity is
proportional to amount.
Used
primarily for analyzing solid samples. |
| Instrument:
Canberra DSA 2000 Gamma Ray Spectrometer
Applications
Measures the amount and energy of high-energy particles
emitted from radioactive substances.
Used for determining identity and amount of radioactive isotopes
found in samples.
