Facilities

UEBL Clean Room

The Urban Environmental Biogeochemistry Laboratory encompasses several different laboratories within Smith Hall.

4th floor labs

The ICP-MS lab houses the Thermo (VG) PQ Excell ICP-MS system and the GBC Optimass 9500 ICP-TOFMS, including the LSX-213 laser ablation system.  Student workstations provide computer access for research projects. A metals-free clean room within this lab allows for contamination-free sample preparation.

The X-ray lab houses the X-ray fluorescence spectrometer and an X-ray diffractometer, which is not part of UEBL. However, because of extensive collaboration between the various groups and departments within the College, most of the analytical instrumentation is available for use by those in need.

5th floor labs

The environmental/analytical research lab is shared by several faculty members.  This lab provides bench and hood space for sample preparation and analyses, such as pH determination.

The chromatography/spectroscopy labs house the ion chromatograph, CN analyzer, two HPLC systems, AA, and two GC/MS systems, as well as a Cary 50 UV-Vis spectrophotometer and a Horiba Jvon FluoroMax-4 spectrofluorometer.

1st floor lab

The first floor lab is used for bulk sample preparation. It contains several drying ovens and furnaces, a freeze-dryer, a ball mill for grinding samples, a hydraulic press for XRF pellet preparation, a fused bead preparation area for XRF, and a cryotome for biological sample preparation.


Instrumentation


Thermo PQ Excell ICP-MS
The Thermo (VG) PQ Excell ICP-MS system measures concentrations of inorganic elements as well as isotopic ratios. A CETAC ASX-520HS auto-sampler allows for unattended operation.


Bruker AXS S4 Explorer
The Bruker AXS S4 Explorer wavelength-dispersive X-ray fluorescence spectrometer measures elemental concentrations. Samples are either dissolved and made into a glass fusion bead or pressed as pellets for analysis. Almost any material that can be prepared in this manner can be analyzed by the XRF. A built-in auto-sampler allows for unattended operation.


The Shimadzu Prominence HPLC system characterizes and quantifies organic molecules, such as pesticides or caffeine, in the liquid phase. The system is equipped with a photo diode array detector (PDA), which is ideal for research and instructional use because of its capability to collect data over a range of wavelengths. The system also has a fluorescence detector for enhanced sensitivity. An auto-sampler allows for unattended operation.


The Agilent 1200 series HPLC system characterizes and quantifies organic molecules in the liquid phase.  It is equipped with a pump wash, external injection valve, auto-sampler, heated column compartment, PDA and fluorescence detectors, and a fraction collector.


Dionex IC25 ion chromatograph
The Dionex ICS-5000 ion chromatograph characterizes and quantifies anions, such as chloride, nitrate, and sulfate, and cations, such as sodium, potassium, and calcium, in liquid samples. A Dionex AS auto-sampler allows for random-access sampling and selection of injection volume.


The Shimadzu TOC-Vcsh NC analyzer quantifies total nitrogen, total carbon, and total organic carbon in liquid or solid samples.


Thermo S4 atomic absorption spectrometer
The Thermo S4 atomic absorption spectrometer has both flame and graphite furnace (GFAA) capabilities for analysis of inorganic elements. It is equipped with a VP100 vapor phase introduction system that can be used for mercury, arsenic, and selenium analyses.


The Agilent 7890A/5975C GC/MS system characterizes and quantifies organic molecules in the gas phase.  This instrument is also equipped with an ECD detector for environmental analyses.

The GBC Optimass 9500 ICP-TOFMS measures concentrations of inorganic elements as well as isotopic ratios.  A CETAC LSX-213 laser ablation system allows for the measurement of solid samples, and a GeoMed Analytical Cryocell 10 coupled to the laser ablation system allows for the measurement of solid biological samples.
