Field analysis of mercury in water, sediment and soil using static headspace analysis

Description: We developed a field screening method for rapid analysis of Hg in water, soil, and sediment, which can be applied cost-effectively at Hg-contaminated sites. Samples are chemically pretreated in ordinary containers, followed by analysis of the sample headspace Hg vapor using a portable commercial analyzer. Hg in water samples is reduced directly by the addition of stannous chloride, while solids are first digested with aqua regia or piranha solution to liberate the Hg from the solids. Aided by v… more

Maintaining data quality in an environmental testing laboratory

Description: In today's competitive and highly litigious world, it is critical that any laboratory generating data for the environmental and allied industries have a world-class Quality Assurance Program. This Plan must conform to the requirements of every agency and client with whom the lab does business. The goal of such a program is data defensibility; i.e., data validity. Data (usually qualitative analyte [compound or element] identifications and quantitative numerical results) are the end results of ne… more

Separation and collection of iodine, sulfur, and phosphorous anion complexes for subsequent radiochemical analysis

Description: We developed a method to separate anion complexes of sulfur, iodine, and phosphorus to enable determination by radiochemical techniques. This method involves ion chromatographic separation of the anion complexes from other highly emitting radioactive species such as cesium-137 and strontium-90 which interfere with radiochemical analysis. We essentially use the ion chromatograph as a sample pretreatment method. The samples are injected onto a cation exchange column which allows the anions to pas… more

Towards ultrasensitive isotope trace analysis {sup 41}Ca.

Description: An Atom Trap Trace Analysis (ATTA) system based on the technique of laser manipulation of neutral atoms is being developed to count individual {sup 41}Ca atoms present in natural samples with an isotopic abundance of 10{sup -15}. Trapping of all stable calcium isotopes has been demonstrated and single-atom counting has been realized. For the most abundant isotope, {sup 40}Ca (97% isotopic abundance), a magneto-optical trap (MOT) loading rate of 2 x 10{sup 10} atoms/s has been reached at the ove… more

High-Performance Computing for the Study of Earth and Enviromental Science Materials Using Synchrotron X-Ray Computed Microtomography

Description: Synchrotron x-ray computed microtomography (CMT) is a non-destructive method for examination of rock, soil, and other types of samples studied in the earth and environmental sciences. The high x-ray intensities of the synchrotron source make possible the acquisition of tomographic volumes at a high rate that requires the application of high-performance computing techniques for data reconstruction to produce the three-dimensional volumes, for their visualization, and for data analysis. These pro… more

Resonant laser ablation ion trap mass spectrometry -- Recent applications for chemical analysis

Description: Resonant Laser Ablation (RLA) is a useful ionization process for selectively producing gas phase ions from a solid sample. Recent use of RLA for mass spectrometry by this group and by others has produced a wealth of knowledge and useful analytical techniques. The method relies upon the focusing of modest intensity laser pulses ({le} 10{sup 7} W {center_dot} Cm{sup {minus}2}) upon a sample surface. A small quantity of material is vaporized, and atoms of desired analyte are subsequently ionized b… more

Characterizing electrodynamic shakers

Description: An electrodynamic shaker is modeled as a mixed electrical/mechanical system with an experimentally derived two port network characterization. The model characterizes the shaker in a manner that the performance of the shaker with a mounted load (test item and fixture) can be predicted. The characterization depends on the measurements of shaker input voltage and current, and on the acceleration of the shaker armature with several mounted loads. The force into the load is also required, and can be… more
