Inductively Coupled
Plasma (ICP) Spectrometer
TJA IRIS Advantage/1000
The ICP is for elemental analyses in water and
solution systems. We have a TJA
IRIS Advantage/1000 Radial ICAP Spectrometer as shown at left. It has
a Solid State CID Detector, which can simultaneously analyze a sample for
multiple elements. It is a time and cost efficient system for elemental
analysis.

Elemental Analyzer
Carlo Erba NA1500
The Carlo Erba NA1500
elemental analyzer simultaneously determines the total carbon and nitrogen
in a wide range of organic and organometallic chemicals. Most commonly in
the EM-1 lab it is employed for the analysis of soils and plant tissue
samples. |

Discrete Analyzer
WestCo SmartChem 200
The
WestCo SmartChem 200 discrete analyzer is an automated spectrophotometer
that almost completely replaces the Alpkem Flow Solution IV within the facility.
The Alpkem will only be used occasionally for long nitrate runs, or as a
backup to the discrete analyzer. The SmartChem 200 is capable of a
number of different measurements, but its primary function will be to
measure various forms of nitrogen and phosphorus in solution. |

Gas Chromatograph
Shimadzu GC-14A
The Shimadzu GC-14A gas chromatograph is
equipped with FID (with methanizer) and ECD (Ni63) detectors and is set up
for analysis of N2O, CH4 and CO2. The instrument is designed for
analysis of CH4, CO2, and N2O in concentrations close to atmospheric
concentrations, although with suitable standards much higher
concentrations of these gases can be analyzed.
The Shimadzu EZChrome data
collection system is run on a Dell Optiplex Gxi 233Mhz computer. |

Total Organic Carbon
Analyzer
Shimadzu TOC-5000A
The
Shimadzu TOC-5000A with autosampler is capable of four different
measurements on filtered samples in solution: Total Carbon (TC), Inorganic
Carbon (IC), Total Organic Carbon (TOC) and Non-Purgeable Organic Carbon (NPOC).
The instrument is PC
controlled by a computer. |

Ion Chromatograph
Dionex DX-500
This instrument is for
determination of polar and ionic species in water and solution systems.
The Dionex DX-500 Ion Chromatograph in the center has a conductivity
detector and is capable of using electrochemical and UV detectors.

Freeze Dryer
Labconco FreeZone 4.5
The FreeZone 4.5L Benchtop Freeze Dry System is a
compact laboratory lyophilizer with ice holding capacity for light to
moderate sample loads. It has a permanently-installed 10-port drying
chamber and a compact benchtop design. This instrument removes water
from frozen materials by converting frozen water directly into its vapor
without the intermediate formation of liquid water. |
Schedule |
 |
Mercury Analyzer
Tekran®
Series 2600
The Tekran® Series 2600 system allows the analysis of ultra-trace
levels of total mercury in liquid samples. It offers unparalleled
sensitivity and flexibility for those who require truly sensitive total
mercury analysis. |
Schedule |
|
 |
Continuous Flow Autoanalyzer
Alpkem
Flow Solution IV
The Alpkem Flow Solution IV with autosampler is equipped
with nitrate/nitrite, ammonia/TKN, and orthophosphate cartridges allowing
for a variety of measurements of different forms of nitrogen and
phosphorus in solution. The WinFlow 4.01 data collection software is run
on a HP Vectra VL7 computer. |

CEM
MarsXpress Microwave Digester
To
transform solid samples into liquids for elemental analyses on other
instruments. This instrument is housed in the basement of Green Earth
Sciences. |
Schedule |
|
No-Fee Instruments:
-
Spectrophotometer (Hitachi U-2000): This is a
bench top UV/VIS spectrophotometer equipped with a sample sipper, which
operates over a range of 200nm to 1000nm. The Plymovent snorkel exhaust
above the Alpkem autoanalyzer can be extended and positioned over the
spectrophotometer when acetone or other solvents are in use.
-
Acid Block Digester (SI Scientific AIM 500):
To transform solid samples into liquids for elemental analyses on other
instruments.
-
Water Purification System (Barnstead Epure 4
Module): To produce high quality and purity analytical grade water
for chemical analyses.
- Balance (Mettler Toledo PR503): Analytical
grade.
-
Atomic Absorption Spectrophotometer: For
elemental analyses of liquid samples. It can usually handle one element
at a time. This instrument is housed in Herrin, Room 488.
