Principle 4 Use of water molecules in the O-H bond and other pan-frequency vibration or rotation of the near-infrared light absorption properties, built by chemometric methods Li relationship wheat near-infrared spectroscopy and its moisture content between the calculated moisture content wheat samples.5 Equipment5.1 NIR analyzer. Add OILS NIR network equipment should comply with GB/T 24895 requirements. No added OILS near infrared Analysis of network equipment, verify eligibility in accordance with GB/T 24895 in the provisions relating to the calibration model validation. 5.2 sample grinding equipment (applicable to the determination of powdered samples NIR analyzer). Preparation of samples for whole wheat flour, crushed samples of grain Distribution and uniformity should be consistent with the requirements established NIR analyzer calibration model when. When modeling and calibration and verification should be used when using The same preparation procedure.6 Determination6.1 preparation before the test 6.1.1 Sample collection and decimation executed according to the provisions of GB 5491. 6.1.2 Sample finishing to remove impurities in the sample and broken kernels. 6.1.3 according to the near-infrared analyzer (5.1) specification requirements for instrument self-test and warm-up test. 6.1.4 In use, at least a day of near infrared analyzer (5.1) monitor with a monitor samples, samples of crude protein of the same monitor Content (dry basis) compared with the initial measurement result of the measurement results, the absolute difference should be less than 0.2%. Compliance monitoring samples prepared in accordance with Appendix A of Scheduled execution. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 24898-2010_English be delivered?Answer: Upon your order, we will start to translate GB/T 24898-2010_English as soon as possible, and keep you informed of the progress.
