Analytical Services

We have a pair of segmented flow analyzers routinely used for determining nutrients in water and soil extracts. A variety of other automated and semi-automated colorimetric assays (e.g., total phenolics, enzyme activity) may be automated on these instruments as well.

Our lab is equipped with a Perkin-Elmer ELAN DRC-e ICP/MS which may be operated in standard mode, or with a dynamic reaction cell. This instrument allows for the determination of metals, metalloids, and their isotopes in aqueous or digested samples down to ppt concentrations.

Our Millenium DMA-80 is used to quantitate total mercury in solid samples to exceedingly low concentrations (ng/kg).

Stable isotopes of carbon, nitrogen, oxygen, and hydrogen are determined on a Finnigan Delta V mass spectrometer. Samples can be introduced through an elemental analyzer, Gas Bench, GC/MS, or TOC analyzer.

When stable isotopes are not required, our three elemental analyzers can be run as standalone instruments to provide CHN and CN-OH analyses.

We use a Thermo Trace 1310 gas chromatograph equipped with a both a SSL inlet and a combination purge and trap, dynamic headspace, and thermal desorption frontend. A Thermo ISQ-LT single quadrupole mass spec provides quantitative and qualitative analyses of volatiles and semivolatiles. Both the SSL and the PT/TD frontend can be used for compound-specific isotopic analysis with unambiguous compound ID (irm-GC/MS).

We offer both preparative and analytical HPLC capabilities with UV-Vis and refractive index detection.

We have both single- and triple-quadrupole LC/MS capabilities for the determination of small molecules (m/z 10-3000).
