Capabilities

1. Shimadzu Gas Chromatography – Mass Spectrometer: GCMS-QP 2010

The SHIMADZU GCMS-QP 2010 can be used in the analysis of the alkylphenolethoxylate nonionic surfactant compounds that are persistent indicators of wastewater and other representative compounds of food additives, antioxidants, fire retardants, plasticizers, industrial solvents, disinfectants, fecal sterols, polycylic aromatic hydrocarbons, and high use domestic pesticides in domestic and industrial wastewater. It also can be used in analysis of pesticides in drinking water, direct analysis of water samples for organic pollutants.

2. Agilent High-Performance Liquid Chromatography: HPLC 1200 series system

The AGILENT HPLC 1200 series system consist of a quaternary pump, auto sampler, degasser and column department. The HPLC 1200 series system can be used for analysis of pesticides and chlorinated phenoxy acid herbicides in drinking water, analyzing polycyclic aromatic hydrocarbons (PNAs) with gradient LC separations.

3. Shimadzu Total Organic Carbon Analyzer: TOC-L series of TOC analyzer

The SHIMADZU TOC-L series of TOC analyzers provide an ultra wide range of 4μg/L to 30,000 mg/L with a detection limit of 4 μg/L through coordination with NDIR. In addition, the combustion catalytic oxidation method makes it possible to efficiently oxidize not only easily-decomposed, low-molecular-weight organic compounds, but also hard-to-decompose insoluble and macromolecular organic compounds.

4. DIONEX Ion Chromatography System: The ICS-5000 system

The ICS-5000 system can be used in determination of trace concentrations of disinfection by-product anions and chlorite, bromate, bromide, and chlorate in drinking water, determination of inorganic cations, anions and ammonium in environmental waters, and determination of total phosphorus in wastewater.

5. Shimadzu UV-VIS Spectrophotometer: UV-1800 UV-VIS spectrophotometer

The UV-1800 UV-VIS spectrophotometer equipped with a variety of measurement modes of photometric mode, spectrum mode, quantitation mode, kinetics mode for determining enzymatic activity and numerous functions as standard in biomethod mode (provided as standard) with capability of analyzing DNA and proteins using the quantitation methods.

6. Computing Cluster: HP ProLiant ML370 G6

A computer cluster can provide many more CPUs but requires a multi-processing management system called MPI. With MPI, the CAMx modeling grid is divided into sub-regions that are processed on separate servers within a cluster and integrated by passing large data messages among the servers. CAMx with MPI allows for improved turn-around by reducing modeling run time from the current 2 hours per episode day for Houston.

7. Thermo Scientific High-Volume Air Sampler

The Thermo Scientific High Volume Air Sampler is designed for high volume air sampling. It can be configured for the measurement of airborne particulates for PM10, PM2.5, or Total Suspended Particulates (TSP) with a variety of inlet options.

8. The Caltech Active Strand Cloudwater Collector version 2 (CASCC2)

The Caltech Active Strand Cloud Collector Version 2 (CASCC2) is an active fogwater / cloudwater collector with Teflon strand collection surfaces and a fan to pull the air past the strands. Air is drawn by a fan through the collector and across 6 rows of inclined 508 µm Teflon strands. Cloud droplets are impacted upon the Teflon strands where they coalesce and, aided by aerodynamic drag, run down the strands and through a Teflon collection trough and Teflon tube into a collection bottle. CASCC2 has been used in numerous fog/cloud chemistry studies by research groups all over the world.

9. The URG’s Annular Denuder System (University Research Glassware)

URG’s Annular Denuder System collects both acidic and basic gases for air quality characterization. The URG’s Annular Denuder System is currently being used in a wide range of research, industry and government studies. The URG annular denuder/filter pack assembly can be used to simultaneously collect Particles and trace gases for chemical analysis.
