Facilities

UEBL Clean Room

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

1st floor labs

In 2010, the UEBL was awarded a $1.4M National Science Foundation ARI grant (# 0963263) to renovate space on the first floor of Smith Hall. Supplemented by funds from TU, these renovations have recently been completed and the renovated space opened for use in October 2012.  This space provides the ideal infrastructure for the multi-disciplinary approach to science that is the foundation of all UEBL activities. Renovated spaces include a sample intake lab, a clean sample processing lab, an instrument lab and two exposure labs. The arrangement of the facilities creates a logical work flow from sample intake through instrumental analysis. The design of the facilities incorporates modern laboratory best practices and an appealing openness accomplished with a liberal use of glass replacing opaque concrete walls, creating a more welcoming and safe environment for faculty and student research.  The renovations also emphasize energy efficiency including the use of non-incandescent lighting systems with motion sensors, and well-balanced HVAC systems.   Photographs of the new lab space can be seen here.

Instruments housed in the new lab suite include the ICP-MS, XRF, CN analyzer, and Shimadzu HPLC.

4th floor lab

The 4th floor lab houses 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 cleaner sample preparation.

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, Agilent HPLC system, AA, two GC/MS systems, two UV-Vis spectrophotometers, and a spectrofluorometer.

 


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.
