Oil and moisture content testing of feed (desktop nuclear magnetic resonance analyzer)

Measuring the oil and moisture content of feed is very important for feed quality control. Due to the high cost of raw materials, the oil content of feed directly affects the quality of the product.

The particle size of feed produced by feed factories varies, and the oil and water content also differ. The oil content is generally less than 40%, and the water content is generally less than 10%. In feed, water is generally combined with the matrix, while oil is in a free state. Therefore, by setting appropriate parameters, the nuclear magnetic signals of oil and water can be distinguished, and the oil content and water content can be obtained in one test.

Low field nuclear magnetic resonanceIt is a fast and convenient oil-water content detection technology that is easy to calibrate, and the shape and appearance of the sample do not affect the detection results.

Solvent extraction technology is a traditional detection method commonly used to test fat content. However, the extraction method testing process is slow, the extraction solution is generally toxic chemical reagents, and requires professional technicians, resulting in significant human error in the test results.

The instrument detection method is commonly referred to as secondary detection technology, as secondary detection technology typically detects unknown samples through calibration lines. Low field nuclear magnetic resonance technology has been used for oil and water content detection for decades, and this technology can be used for testing the oil-water content of feed.

Oil and moisture content testing of feed (desktop nuclear magnetic resonance analyzer)It has the following advantages:
1. The production of markings is simple;
2. The appearance and shape of the sample do not affect the test results;
3. The testing process causes no damage to the sample, and the sample can be reused;
4. Fast testing speed, usually completed within 1-3 minutes;
5. Can simultaneously determine the oil content and water content;
