Commercial Sample Analysis

Our laboratory conducts analysis of commercial plant, tissue and soil samples for Carbon, Nitrogen and Phosphorus. Rates are listed below, with Internal Rates charged to FIU accounts. We analyze Carbon and Nitrogen on a CE Flash 1112 Elemental Analyzer. We analyze Phosphorus on a UV-2101 Shimadzu Spectrophotometer using a modified colorimetric method from Solorzano and Sharp (1980). Analysis time varies based upon the current queue, but is typically < 2 months. For more information about commercial sample analysis, please contact Dr. Jim Fourqurean at
