 |
Instrument
|
Nuclear magnetic resonance spectrometer (NMR) |
|
Model
|
JEOL JNM-ECP400
FT NMR
|
|
Applications
|
Technique is similar to MRI. Provides detailed structural information for the identification of
organic compounds. |
| Instrument |
Inductively coupled plasma/atomic emission spectrometer
|
 |
|
Model
|
JY 38 S |
|
Applications
|
Concentrations of cations, including metals, at low levels
in environmental and other kinds of samples
|
 |
Instrument
|
Time-resolved
fluorescence spectrometer
|
|
Model
|
Photon Technology International
QM-2000 and C-720;
GL-302 dye laser
|
|
Applications
|
Laser excites sample; analyte molecules fluoresce at
specific wavelengths. Analysis of biomolecules and organics. Both steady-state and time-resolved techniques.
|
| Instrument |
Particle analyzer
|
 |
|
Model
|
Micrometrics SediGraph 510 |
|
Applications
|
Measures the size distribution of small particles in
environmental and other samples.
|
 |
Instrument
|
High-pressure liquid chromatograph/mass spectrometer (HPLC
and LC-MS) |
|
Model
|
Waters 2690 separations module; Waters 996 photodiode array
detector; Micromass ZMD 4000 |
|
Applications
|
Separation and analysis of organic liquids
and aqueous solutions. The
mass spectrometer allows determination of the species present from the
mass. |
| Instrument |
Microwave digester
|
 |
|
Model
|
CEM Mars 5 |
|
Applications
|
Rapid preparation of samples of all kinds for analysis by instrumental
methods
|
 |
Instrument
|
Ultra-violet/visible spectrometer (UV/vis) |
|
Model
|
Varian Cary 300 Bio |
|
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 |
DNA sequencer
|
 |
|
Model
|
Applied Biosystems Gene Amp PCR 9700 |
|
Applications
|
Allows
for the automatic analysis of gene sequences.
|
 |
Instrument
|
Ion chromatograph |
|
Model
|
Dionex DX 500 with autosampler |
|
Applications
|
Identification and quantification of anions in solution,
such as environmental samples |
| Instrument |
Gas Chromatograph- Mass Spectrometer (GC-MS)
|
 |
|
Model
|
Agilent 6890 GC; 5973 mass selective detector |
|
Applications
|
Identification and quantitation of most organic compounds in
environmental, research, and other samples.
|
 |
Instrument
|
X-ray fluorescence spectrometer (XRF); X-ray diffractometer
(XRD; not pictured) |
|
Models
|
Rigaku RIX 2100 XRF; Rigaku Minflex XRD |
|
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 |
Gamma ray spectrometer
|
 |
|
Model
|
Canberra DSA 2000 |
|
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.
