Product Introduction:

PQ001（Nuclear Magnetic Resonance Oil Content Tester _ Nuclear Magnetic Resonance Analyzer）It was officially launched in 2008 and has undergone several upgrades and replacements. The product has been maturely applied in routine testing and research such as oil and moisture content and solid fat content determination in food and agriculture. Research and analysis can be conducted on multiple indicators such as moisture distribution and migration during preservation, storage, refrigeration, freezing, and thawing processes in the food industry. Research on the relative proportion of moisture in different phases of food, moisture characteristics, and analysis of water migration mechanisms during experimental refrigeration and freezing processes. PQ001 has the characteristics of small size, high precision, good repeatability, good stability, and high cost-effectiveness. （Nuclear Magnetic Resonance Oil Content Tester _ Nuclear Magnetic Resonance Analyzer）

Analysis of the advantages and disadvantages of nuclear magnetic resonance oil content analyzer and Soxhlet extraction method for determining oil content:
The determination of oil content in seeds such as soybeans, rapeseed, sesame, corn, cottonseed, sunflower seeds, peanuts, wheat, tung seeds, etc. is an important step in quality inspection. The determination of oil content in seeds can be analyzed by using a nuclear magnetic resonance oil content analyzer and conventional Soxhlet extraction method, both of which are used in seed determination Below is a brief overview of the advantages and disadvantages of these two methods.

Analysis of the disadvantages of the Soxhlet extraction method:
1. Low efficiency, measuring for several hours or even ten hours at a time, and the number of samples measured simultaneously is limited;
2. Harm the body and pollute the environment; Testing requires a large amount of toxic chemical reagents, which not only pose significant hazards to operators but also pollute the environment;
3. There are significant human factors involved in chemical methods, which can lead to large errors. Often, the results of the same sample produced by different people can vary greatly;
4. Waste resources, measurement requires a large amount of water, electricity, chemical reagents, manpower, etc;

Nuclear magnetic resonance oil content analyzer（）：
1. Fast testing speed, high accuracy, good stability and repeatability, no damage to samples, can achieve automated and intelligent testing, and use intelligent classification detection methods for different species, with each measurement taking only a few minutes;
2. Less manual intervention: The software automatically completes frequency adjustment, with humanized step-by-step prompts to guide the operation process. It contains innovative self-locking frequency technology, which does not require manual intervention, is easy to operate, and does not introduce human errors;
3. Strong anti-interference ability: can work in environments with strong electromagnetic interference;
4. Strong customization: Users can configure the mode, and the printed content is more flexible and rich. It can not only be directly saved on the machine, but also saved through a USB flash drive and opened for processing on the computer.
