Principle 4 Use fat molecules in the C-H, N-H, O-H bond and other pan-frequency vibration or rotation of the near infrared light absorption, chemical meter Methodology to establish correlation between the amount of corn Near Infrared Spectroscopy and its fat content between the calculation of fat content of corn 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). particle size distribution and homogeneity of the crushed sample should be consistent with the past Infrared analyzer calibration model established requirements when, should be used when using the same manufacturing process and model calibration and verification.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 the case where the state of at least a day of near infrared analyzer (5.1) monitoring once with monitoring samples. It should track and monitor the results every day, The measurement results of the same sample monitoring compared with the initial measurement result, shall ensure compliance with the provisions of 9.2. Monitor sample preparation in accordance with Appendix A Regulations. 6.1.5 The monitoring sample measurement results do not meet the requirements of 9.2, should stop using, and reported to the network administrator or equipment suppliers to be adjusted ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 24902-2010_English be delivered?Answer: Upon your order, we will start to translate GB/T 24902-2010_English as soon as possible, and keep you informed of the progress.
