摘要
研制出了一种可用于商品玉米中水分、蛋白质、脂肪和淀粉含量现场快速检测的便携式短波近红外分析仪;讨论了仪器各部件的结构和性能,通过现场检测商品玉米及与国家标准方法测定结果的比较研究,证明该仪器对玉米中水分、蛋白质、脂肪的测定误差不大于0.5%,对淀粉的测定误差小于1.5%,表明该仪器已达到在现场进行准确、快速检测的要求。
A kind of portable short-wave near infrared spectrometer, Model SWNLR-100 Corn Component Fast Analyzer, is developed, which can measure moisture, protein, oil and starch in commercial tom samples without any pretreatment. Each part of them and： their performance are introduced. The analyzer has been applied to analyze commercial corn on-site and the results were compared with that obtained with GB methods of China. Furthermore, the analytical error caused by the analyzer is no more than 0.5% for determining moisture, protein and oil, and is less than 1.5% for starch. The performance of the analyzer shows it meets the requirement for an accurate and quick analysis on-site.
