Principle 4 Use of protein molecules in the C-H, N-H, O-H, C-O bond and other pan-frequency vibration or rotation of the near-infrared light absorption Characteristics, establish the correlation between rice by near infrared spectroscopy and crude protein content between using chemometric methods to calculate rice and other samples of crude protein White content.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 Sample Preparation6.1 GB 5491 by the method of laboratory samples and sample a test sample. 6.2 The test sample according to GB/T 5494 method for removing impurities, broken grains and brown rice outside the valley, a net rice, or rice into the net prepared rough Rice, rice test sample.7 Determination7.1 preparation before the test 7.1.1 warm-up and self-test instrument, in use state at least a day of near infrared analyzer (5.1) to monitor a sample with monitoring, control samples ...... |
