Analytical Instrumentation

Inductively Coupled Plasma – Optical Emission Spectrometer

Perkin Elmer Avio 560 MAX

Capable of quantitative analysis of most elements in waters or soil/plant/animal extracts. This ICP-OES performs both radial and axial plasma views and has a high-throughput valve system for rapid analysis.

Total Carbon/Nitrogen Analyzer

Shimadzu TOC-L and TNM-L

A combustion catalytic oxidation analyzer for total organic carbon (TOC), total inorganic carbon (TIC), and total nitrogen (TN) analysis of waters and soil extracts.

Flow-Injection Analyzer

Lacht QuikChem 8500 Series II

A flow-injection analyzer with 4 channels that performs colorimetric, conductometric, and turbidimetric analysis on a variety of different method for water or extracts.

Flow-Injection Analyzer

FIAlab FIAlyzer-FLEX

These provide colorimetric analysis for inorganic nutrients in waters and soil extracts. We utilize two independent arrays, with 6 total analyzers that can simultaneously perform low-level nutrient analysis of seawaters and higher concentrations in soil or plant extracts.

Cavity Ring-Down Spectrometer

Picarro L1102-i

Performs high-precision isotopic analysis of δ2H (δD) and δ18O of water.

Continuous-Flow Isotope ratio Mass Spectrometer

Thermo Delta V Advantage

Analyzes isotopic ratios of all stable light isotopes (2H, 12C, 15N, 18O and 34S) prepared by the EA or Gasbench II systems and supplied through a Conflo IV.

CHNOS Elemental Analyzer

Thermo Flash EA IsoLink

Combustion/reduction reactors convert organic matter from plant, animal, soils, and sediments to GC separated gasses to measure concentrations via a thermal conductivity detector and supply sample gases to the IRMS for isotopic analysis.

Headspace Gas Analyzer

Thermo Gasbench II

Gas preparation device for the headspace analysis of δ2H and δ18O of water, δ13C and δ18O of carbonates/dissolved inorganic carbon (DIC), and atmospheric gas analysis.

CN Elemental Analyzer

Thermo Flash EA 1112 NC Soil Analyzer

Conducts analysis of bulk (%) carbon and nitrogen in solid samples of soils, sediments, and plant or animal tissue. THis EA is also interfaced to the IRMS to provide δ13C and δ15N isotopic data.

Gas Chromatograph

Agilent 7890B

Performs gas analysis using a Flame Ionizing detector (FID) and a Micro-electron capture device (Mirco-ECD).

Laser Scanning Particle Size Distribution Analyzer

Horiba Partica LA-960

Measures particle size distributions for powders, suspensions, or emulsions. Used primarily for soil texture analysis and distribution in the USDA soil classification system.

Scintillation Counter

Beckman Coulter LS 6500

Automated quantification of radioactivity in radioactively-tagged samples by measuring light emitted from decay-produced ionizing particles.
