Available laboratory procedures and equipment for chemical analyses include but are not limited to soil:

  • Simultaneous multi-element analysis of metals, transitional metals, metalloids and other elements in liquid matrices using PerkinElmer Optima 7300 DV Simultaneous Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES).
  • Halides (Br-, Cl- and F-), oxyanions (NO2-, NO3-, PO43-, SO3- and SO4-), alkali and alkaline earth cations using a Dionex™ 500 can be expanded to include the determination of additional inorganic anions and organic analytes such as carboxylic, sulfonic, and phosphonic acids; and primary, secondary, tertiary, and quaternary amines).
  • Silicon, silicate, iron, aluminum, nitrate, nitrite, ammonia, total Kjehldahl nitrogen (TKN), total dissolved nitrogen, ortho-phosphate, and total dissolved phosphorus, molybdenum etc. using the principle of flow injection analysis (FIA) colorimetric system: Lachat QuikChem® FIA + 8000 with an XYZ autosampler. (Application of QuickChem® 8000 can be expanded to include pH, acidity, alkalinity, boron, bromide, fluoride, iodide, calcium, potassium, copper, chlorate, chlorite, chromium -- hexavalent, magnesium, manganese, sulfate, sulfide, sulfite, uranium, zinc and many others).
  • Dissolved organic and inorganic carbon (DOC & DIC), Non- purgeable organic C (NPOC), total dissolved carbon, and elemental carbon using Shimadzu™ Total Organic Carbon Analyzer TOC-5000A with solution and solid sample modules and equipped with an infrared detector to measure CO2.
  • Elemental carbon, hydrogen, nitrogen, sulfur, and oxygen (CHNS-O) using a CEInstruments (Thermo Electron Corp) Elemental Analyzer EA 1110 with thermal conductivity detector (TCD).
  • Analysis of compounds using Shimadzu UV-3101PC UV-VIS-NIR Scanning Spectrophotometer with wavelength: 190nm~3200nm and with spectrum, photometric and kinetic modules.
  • Analysis of about one-half of the elements in the periodic table as dissolved ionic species, polyatomic ions, complexes of ions, or organic compounds using Voltammeter - Metrohm 797 VA Computrace.

Available laboratory procedures and equipment for physical measurements include but are not limited to soil:

  • Moisture retention curve or water release characteristic curve, available water capacities, wilting point, air capacity using Soilmoisture PM Compressor FSM Jenny Pressure Plate Apparatus capable 0 to 15 bar pressure.
  • Hydraulic Conductivities: Saturated and/or unsaturated hydraulic conductivity/diffusivity by constant and falling head method and ku-pF Apparatus DT 04-01 UGT model (the only one of its kind in USA).
  • Gravimetric water content - mass of water per unit mass of dry soil using oven with 100-110 °C temperature control.
  • Bulk density - the ratio of the mass of the solid phase of the soil (i.e., dried soil) to its total volume (solid and pore volumes together) by core method in which a known volume of undisturbed soil sample is dried and weighed (gravimetric method).
  • Soil compaction by penetrometer resistance.
  • Particle size analysis (Sand/Silt/Clay, Stones) using hydrometer apparatus and sieves.
  • Aggregate stability - ability of soil aggregates to resist disruption when outside forces (usually associated with water) are applied is determined by repeated agitation of the aggregates in distilled water.
