Measuring protein in wheat and barley

NIR Technology Australia has obtained a certificate of Pattern Approval for the Cropscan 2000 NIR Analyser. Pattern Approval is a national standard for testing equipment and is designed to certify a specific instrument for measuring under a defined set of environmental conditions.

The Cropscan 2000B NIR Analyser measures protein and moisture in whole grains, including wheat, barley, soybean, corn and sorghum. The NMI Pattern Approval certifies that the Cropscan 2000B is suitable for use as an instrument to measure protein in wheat and barley for trading purposes.

The Pattern Approval process requires that the instrument be able to make a measurement of protein in wheat with a maximum permissible error (MPE) of 0.4% and in barley with an MPE of 0.5%. The conditions under which these measurements are tested include: instrument temperature between 10 and 40°C; humidity 85% RH exposure for two days; mains voltage (-15 to +10% variation in mains voltage); electrical burst; electromagnetic fields; and electrostatic discharge.
