iCap 7600 Duo ICP-OES Analyzer
This instrument is used to determine the concentration of several elements simultaneously on a variety of extractions and water samples. The duo view provides improved readings for trace elemental concentrations.
Lachat 8500 Flow Injection Analyzer
This instrument is a flow-injection analyzer which employs colorimetry (or turbidimetry) to determine the concentration of compounds-of-interest in liquid samples, including Water and Extracts from soil, plant, and other materials. Our system is set up for quantification of Nitrate-N, Nitrite-N, Ammonia-N, Total Nitrogen, ortho-phosphate-P, Total Phosphorus, Chloride, and Sulfate-S
Elementar Rapid CS Cube
This instrument is used to determine the percentage of total sulfur in soil, plant, and other solid samples. Samples placed in tin capsules are injected into a high temperature combustion zone and analyzed via IR detection.
Soxtherm Rapid Extraction System
This instrument is primarily used to extract soluble oils from soybean samples. Samples are placed in filter bags within fiber capsules suspended over a solution of petroleum ether. The petroleum ether is boiled and recondensed through multiple cycles until all soluble oil has been collected at the bottom of the vessel.
Elementar VarioMAX C/N Analyzer
This instrument is used for the determination of inorganic and total carbon in soil and other solid materials. For total carbon, the samples are burned at 900 degrees C in an oxygen rich atmosphere and the evolved carbon dioxide is measured by a non-dispersive infra-red detector. For organic carbon, samples are pre-treated with HCl to remove any inorganic carbonates before processing. Inorganic carbon is determined by difference between total C and organic C.
Dionex 120 Ion Chromatograph
This instrument is used for simultaneous anion analysis of Fluoride, Chloride, Nitrate, Nitrite, Bromide, Phosphate, and Sulfate in water. Detection limits for most elements are 0.2 mg/l.
Elementar vario TOC cube
This instrument is used to measure organically and inorganically bound carbon in aqueous solutions by combustion.
SCP Science NovaWAVE
This microwave digestion system assists with the breakdown of soil, plant, and other materials for further ICP analysis. It is also used in determining crude fiber measurements on soybeans. Each sample is monitored for temperature and pressure to ensure complete digestion of the sample. Digest methods are chosen based on the sample type and desired analysis.
Shimadzu GCMS-QP2010 SE
HPLC (Alliance Waters 2695 Separations Module)
Perkin Elmer AAnalyst 100 Atomic Absorption Spectrophotometer
Used to determine potassium in ammonium acetate soil extracts.
Brinkmann PC 900 Probe Colorimeter
This instrument is used for the colorimetric determination of phosphorus in Bray and Olsen soil extracts. It uses a fiberoptic cable in conjuction with a mirrored tip to determine the absorption of light by a colored solution.
