1. Introduction
Nanjing Ruinike Technology
High-pressure digestion tank for grain oil detection, also known as sample dissolver, pressure dissolve bomb, autoclave, and stuffy tank , digestion tank, polytetrafluoroethylene high pressure tank. Our company's digestion tanks have solved the customers' problems of large quantity, high requirements, small size and difficulty in digestion during the digestion process.
In order to ensure the quality and safety of finished grains and oils, a certain city continues to increase monitoring efforts. The annual monitoring of finished grains and oils reaches 1 batch, which is three times that of the previous year. In our daily lives, such as: rice, wheat, barley, soybeans , corn, various oils, various cereals, rice, wheat flour, various edible oils, some industrial oils, noodles, instant noodles, soy sauce, vinegar, etc. contain: harmful heavy metal pollution elements, pesticide residues, fatty acids and trans fatty acids , are also closely related to our health.
Special high-pressure digestion tank for grain oil detection, the temperature can reach ℃ when used in the oven, and it can withstand pressure
The inner cup is made of experimental grade high-purity polytetrafluoroethylene material, or M or material. The outer tank is made of national standard stainless steel, or strong corrosion-resistant Hastelloy, Monel, nickel, and titanium alloys. Moreover, the inner cup can also be equipped with the acid-catching electric heating plate of my unit
which is specially used for acid-catching and digestion in the later stage.
Selected materials, no recycled materials, clean processing environment, optimized processing technology, ensuring extremely low background.
2. Working Principle
High-pressure digestion tank: The use of the high-temperature and high-pressure sealing system (strong acid or alkali) environment in the tank to achieve the purpose of rapid digestion of insoluble substances can greatly shorten the digestion process, and It can minimize the volatilization loss of the measured components and improve the accuracy of the measurement. It is a powerful assistant for digesting samples when measuring trace elements and trace elements.
It is widely used in sample preprocessing for chemical analysis methods such as spectrum mass spectrometry (M), atomic absorption and atomic fluorescence. In food, geology, metallurgy, commodity inspection, nuclear engineering and other systems, it can digest pesticide residues, medicines, food, rare earths, etc. , heavy metals such as b, r, Z,,, H, etc. in various organic matter in aquatic products. Sample pretreatment digests heavy metals, pesticide residues, food, sludge, rare earths, aquatic products, organic matter, etc.
In addition: According to the specific requirements of the experiment, Nanjing Ruinike Technology has also independently developed an imported PTFE inner cup that can withstand higher temperatures, is more resistant to penetration, and is more resistant to deformation
. As well as more corrosion-resistant alloy outer tanks, digestion tanks with anti-corrosion coatings, double-layer inner cups, etc. For example: Gansu Provincial Cereal and Oil Quality Supervision and Inspection Institute, Anqing Cereal and Oil Quality Inspection Station, Tianshui Cereal and Oil Prevention and Control Inspection Center, etc. have received excellent feedback.
3. Features of the high-pressure digestion tank
Good sealing: the inner cup of the high-pressure digestion tank has a concave and convex tongue-and-groove design, and the inner cup lid has a pointed bottom design to facilitate sample collection after the experiment.
, Safety: Unique design, fine workmanship, there is a vent hole on the top of the cup, high safety factor. Even if the temperature is out of control, only the inner cup will be deformed, but the outer can will not be damaged.
It has high digestion efficiency and strong ability. It can digest many samples that are difficult to digest by traditional methods and has wide adaptability.
The element blank value of the inner cup is low, which improves the accuracy and precision of analysis and reduces work intensity and environmental pollution.
The inner cup/outer can is numbered sequentially to facilitate equal opportunity use.
, low cost and easy to use. The investment in the early stage and later stage is very small, the operation is easy, the operator requires almost no training before use, and the maintenance is simple.
The inner cup can be changed to imported polytetrafluoroethylene (the material of the inner tank of the microwave tank)
which is more resistant to penetration and deformation, lower background guarantee, and higher use temperature.
The selected materials for the inner and outer tanks, years of production experience, recognition by many users, quality assurance, and trustworthy.

Our company’s domestically exclusively developed imported polytetrafluoroethylene inner cup
Characteristics
The inner tank is made of high-purity experimental grade imported enhanced modified M material
Compared with: In addition to all the advantages of M, it also has some improved characteristics: lower background guarantee, better resistance to deformation, penetration resistance, and recoverability under high temperature and pressure, and its appearance is closer to jade white
. The maximum operating temperature is d, and the limit can even reach
. Special R&D and production technology ensures the smoothness of the extra-long tanks of special manufacturers (such as M). The inner tanks of microwave digestion instruments of various manufacturers and specifications can be customized and matched with the original factory. The microwave digestion instrument is used
. It is processed by a special process to optimize the processing technology to ensure an extremely low background value (blank value). The manufacturer's processing technology can also affect your experimental results
. For imported microwaves The inner tank matching the digestion instrument is especially the M inner tank which is widely used
. The processed inner cup can be used with other instruments. The experimental data of the product is as good as that obtained from the original import
. Various models of matching M microwave digestion are provided. The inner tank used by the instrument is all made of M material, the lid is made of transparent material, the tube body and gasket are all made of M material, and all materials are available for customers to choose
The only company that can customize the standard equipment of each manufacturer Inner tank, at the same time we promise that the product quality is consistent with the original factory and has the highest cost performance.
Advantages and disadvantages of three commonly used methods for sample pretreatment
Advantages of high-pressure digestion method
: safety, low initial investment, simple equipment, easy operation, small amount of sample and reagents, low blank value, avoid Contamination, sample processing is safe and thorough, with high accuracy, and can process samples in large batches.
Limitations
: The sample processing cycle is slightly longer, the temperature and pressure cannot be controlled, and the appearance is simple.
Advantages of room temperature digestion method
: low investment, simple equipment, easy operation, large amount of reagents, average accuracy, short working cycle, and can process samples in large batches.
Limitations
: Easy to stain, pollute the environment, harmful to the health of operators, poor precision, more reagents used, limitations for some insoluble samples
Advantages of microwave digestion
