Abstract
A small process analyser employing the pulsed n.m.r. technique has been used to determine water in several different flour types and both oil and water contents of a wide range of animal feedstuffs. The procedures used for establishing and eliminating cross‐interferences in these analyses are described. Flour moisture contents in the range 13–15% were determined with approx. 0.2% standard deviation. The measurement time per sample was approx. 1 min. Mixed feeds with 1–14% oil and 7–14% water were determined with standard deviations of 0.2–1.0% and 0.5–1.2%, respectively, depending on the range of compositions employed. Measurement times per sample were 10 seconds for oil and approx. 1 min for water.
