Page 2 of 3 Fhremical Analysis Laboratory ) a a Typical applications: To date, our lab has used this method to analyze protein, soll, water and plant samples. Other applications include detection of trace elements in a wide variety of aqueous matrices (drinking water, river, lake and ground water, waste water and effluent, and seawater) in solids after digestion (sediment, soil, sludge, road dust, air particulate matter, plant tissue and grain, rocks and minerals, etc.) and in samples of body fluids (blood, plasma, and urine) Instrumentation: Thermo VG Instruments PlasmaQuad 3 ICP-MS Atomic Absorption/Emission Spectrometry Analyses of solutions or dissolved solids for the presence of one or two specific elements Detection limits in the parts-per-million to upper parts-per-billion range Requires a minimum sample of 25 mi Typical applications: proteins, plants, soils Instrumentation: Thermo Jarrell-Ash SH1000 Atomic Absorption/Emission Spectrometer HERBICIDE AND PESTICIDE ANALYSIS Analysis requires a 1 ml sample Instrumentation: Finnigan/Trimetrics 9001 Gas Chromatograph Typical applications: plant material, soils, water INORGANIC AND TOTAL DISSOLVED ORGANIC CARBON Determines the concentration of carbon dioxide as well as organic carbon in solution Requires a 10 ml sample minimum Instrumentation: O.I. Corporation Model 700 Total Organic Carbon (TOC) Analyzer Typical applications: aquatic ecology to test the health of a body of water CARBON, HYDROGEN & NITROGEN ANALYSIS Rapid, simultaneous determination of total carbon, hydrogen and nitrogen content of non-aqueous samples Requires 1-3 mg of dry, ground plant or animal tissue and 200 mg of dry 18-40 mesh soils Instrumentation: Perkin-Elmer 2400 Carbon, Hydrogen, Nitrogen Analyzer (CHN) Typical applications: plants, soils, forestry, water, crystalline compounds,’seston, complex carbohydrates, and plastics NUTRIENT ANALYSIS Avallable chemistries are ammonia, chloride, nitrite, sulfate, ortho phosphate, alkalinity, total nitrogen and total phosphorus. Requires a 25 ml sample Instrumentation: Braun-+Luebbe Auto Analyzer II Continuous Flow System Typical applications: water, wastewater OTHER SERVICES Other equipment includes a microwave digestion system, a freeze-dryer for lyophilizing tissue, and a jar mill for grinding samples for low-level metal analysis. The laboratory uses several EPA-approved and AOAC methods for preparation and analysis. —enininmtetintttirarenittntmntenntnatnntnttetinatttititeninsLtNttititisthtiennrntetntentuinnneettennuLinLlinaneNicinnneenenenmteineiee 2005 Office of Research Services at The University of Geargra A, Division of the Office of the Vice President for Research (OVPR) ORS Web Contact / Feedback » http://www.cal.uga.edu/ 5/6/2005 Be
