Subject: The standard deviation of the Infratec instrument using Iowa State University calibrations relative to wet chemistry ... вот контекст:US soybean producers, representing 30 soybean production states, in response to a mailed request, provided samples of 2005 crop soybeans for analysis. Samples received by November 4, 2005 were analyzed for protein and oil contents using an Infratec near-infrared instrument (Foss North America, Eden Prairie, Minn.).
