Central Analytical Laboratory (CAL)
Located in 3079 ALS.
Research in the agricultural, natural resource, and environmental sciences requires timely access to accurate chemical analyses of plants, soils, and waters. We meet this need by providing fee-based analytical services to OSU scientists and cooperating investigators. The CAL also serves as an important resource for Oregon students and extension clientele seeking information and advice about plant, soil, and water analysis.
- Provide chemical analysis of plant tissues, soil extracts, water mixtures, biosolids, and geologic material digests in support of research, teaching, and extension in soil, fertility, plant nutrition, soil chemistry, and earth science.
- Develop and maintain expertise in analyzing soils, plants, and waters for essential ecosystem nutrients as well as elements posing environmental hazards.
- Provide physical analysis of soil materials and geologic substrates in support of research, teaching, and extension in land use and management, ecosystem management, and environmental protection.
- Develop and maintain expertise analyzing soils and geologic materials for intrinsic physical properties.
The Perkin Elmer Optima 3000DV is an inductively-coupled plasma optical emission spectrometer with a diode array detector. The dual view is capable of viewing the plasma axially for improved detection limits, or radially to provide lower matrix effects and fewer spectral interferences. Routine analysis includes P, K, Ca, Mg, Mn, Fe, Cu, B, and Zn and this instrument is capable of running any ICP analyte.
The Leco CNS-2000 Macro Analyzer simultaneously determines carbon, nitrogen and sulfur in solid samples. No digestion or extraction is required. Up to 2g of ground sample can be used for maximum accuracy in heterogeneous samples.
The Alpkem Flow Solution with digital and monochromater detectors provides automated analysis of Total Kjeldahl N, NH4, NO3, Total P, or ortho-P in soil, plant, and water samples. The Random Access Sampler allows simultaneous analysis of 2 analytes and automatic dilution of off-scale samples. This instrument is used primarily for low level detection in water samples.
The Alpkem RFA 300 provides automated analysis of Total Kjeldahl N, NH4, NO3, Total P, or ortho-P in soil, plant, and water samples. This instrument is used primarily for higher concentration levels in soil and plant samples.
