Research Instrumentation

Resources for UVM Research

One mission of our lab is to provide analytical services to University researchers. We are able to house instrumentation that is normally not affordable in individual labs. Analysis is available either by hands-on use or a fee-per-sample basis. Training and support are available. Current Pricing

ICP.AES (inductively coupled plasma atomic emission spectrophotometer) is used for determination of metals (and a few nonmetals) in liquid samples. We now have a Perkin-Elmer Optima DV thanks to an award from the USDA-NRI competitive grants program. This instrument operates both in a radial mode for normal samples and an axial mode for greater sensitivity. Common elements analyzed include Al, Ca, Cd, Cu, Cr, Fe, K, Mg, Mn, Ni, P, and Zn.

Ion Chromatograph (IC) is normally used for the determination of a suite of inorganic anions (F-, Cl-, Br-, NO3-, NO2-, PO42-, SO42-). It can also be used for inorganic cations, organic acids, and more--depending on column choice. The working range is adjustable but usually between 0.05 and 10 mg/L. Our current instument is a Dionex 600DX with a GS50 gradient pump, ED50 electrochemical detector and AS50 autosampler.


CN Elemental Analyzer (carbon and nitrogen) is used for quantification of these elements in solid samples. Sample size is usually 20-100 mg and the working range is 0.1-100%. Samples need to be finely ground for repeatable results.

Flow Injection Autoanalyzer is used for rapid colorimetric analysis. Our current instrument (Lachat QuikChem AE) has manifolds for nitrate, ammonium, phosphate, chloride, and total Kjeldahl digests. Many other colorimetric procedures are available. This instrument can easily process 80-100 samples per hour and is useful for studies that generate large sample amounts.
