iCap 7600 Duo ICP-OES Analyzer
Inductively-Coupled Plasma - Optical Emission Spectrometers are used to determine the concentration of multiple elements simultaneously on a variety of extractions and water samples. Multiple viewing options provide improved readings for trace elemental concentrations.
Lachat 8500 Flow Injection Analyzer
Flow-injection analyzers employ 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 equipped for quantification of Nitrate-N, Nitrite-N, Ammonia-N, Total Nitrogen, ortho-phosphate-P, Total Phosphorus, Chloride, and Sulfate-S.
Elementar Rapid CS Cube
A combustion analyzer 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
A reflux extractor used to extract soluble oils from soybean and other grain samples. Samples are placed in filter bags within fiber capsules suspended over a solution of petroleum ether. The petroleum ether is boiled and condensed through multiple cycles until all soluble oil has been collected at the bottom of the vessel.
Elementar VarioMAX C/N Analyzer
A combustion analyzer used for the determination of organic and total carbon in soil and other solid materials. For total carbon, 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.
Total N is determined by combustion of non-acidified samples via a thermal conductivity detector.
Dionex Integrion HPIC
A high-pressure (high-performance) ion chromatograph used for simultaneous quantification of Fluoride, Chloride, Nitrate, Nitrite, Bromide, Phosphate, and Sulfate in water. Detection limits for most elements are approximately 0.1 mg/l.
Elementar vario TOC cube
A liquid analyzer used to measure organically and inorganically bound carbon and nitrogen in aqueous solutions by combustion.
SCP Science NovaWAVE
A microwave-assisted digestion system for the breakdown of soil, plant, and other materials for 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.
Perkin Elmer AAnalyst 100 Atomic Absorption Spectrophotometer
Used to determine potassium levels in (ammonium acetate) soil extracts.
Brinkmann PC 900 Probe Colorimeter
An oldy-but-goody 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.
