1. Introduction:
Nanjing Ruinike Technology's special high-pressure digestion tank for grain oil testing is also called a sample dissolver, pressure dissolve bomb, autoclave, stuffy tank, digestion tank, PTFE high pressure tank. -- (Wen Li-) Our company's digestion tanks have solved the problems of customers with large quantities, 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 city has continuously increased monitoring efforts. The annual monitoring of finished grains and oils has tripled the number of batches in the previous year. In our daily lives, such as: rice, wheat, barley, soybeans, corn, various Oils, various grains, rice, wheat flour, various edible oils, some industrial oils, noodles, instant noodles, soy sauce, vinegar, etc. contain harmful heavy metal polluting elements, pesticide residues, fatty acids and trans fatty acids, which are also related to Our health is closely related.
The temperature of the high-pressure digestion tank dedicated for grain oil detection in the oven can reach ℃ withstanding pressure
. The inner cup is made of experimental grade high-purity polytetrafluoroethylene, or 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 added, clean processing environment, optimized processing technology to ensure extremely low background.
2. Working principle:
High-pressure digestion tank: The use of the high-temperature and high-pressure sealing system (strong acid and strong alkali) environment in the tank to achieve the purpose of rapid digestion of insoluble substances can greatly shorten the digestion process and make it easier Minimizing the volatilization loss of the measured components and improving the accuracy of the measurement 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 (-), atomic absorption and atomic fluorescence. It is used in food, geology, metallurgy, commodity inspection, nuclear engineering and other systems to digest pesticide residues, medicines, food, rare earths, water, etc. Heavy metals such as, 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 polytetrafluoroethylene
inner cup
that can withstand higher temperatures, penetration and deformation. As well as more corrosion-resistant alloy outer tanks and digestion tanks with anti-corrosion coating 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, vent holes on the top of the cup, high safety factor, even if the temperature is out of control, only the inner cup will deform and the outer can will not be damaged.
It has high digestion efficiency and strong ability to digest many samples that are difficult to digest with traditional methods. It has wide adaptability.
The low element blank value of the inner cup improves the accuracy and precision of analysis and reduces work intensity and environmental pollution.
The inner cup/outer can are sequentially numbered to facilitate equal opportunity use.
, low cost and easy to use. There is very little investment in the early and late stages, and it is easy to operate. The operator requires almost no training before use and is simple to maintain.
The inner cup can be changed to imported polytetrafluoroethylene
(Microwave tank inner tank material)
More resistant to penetration and deformation, lower background ensures higher use temperature.
The selected materials for the inner and outer tanks, many years of production experience, and the quality assurance recognized by many users are trustworthy.

Features: --(Wenli-)
The inner tank is of high purity experimental grade Imported enhanced modified materials
Compared with: In addition to all the advantages of the imported modified materials, it also has some improved characteristics: it has a lower background to ensure better resistance to deformation, penetration resistance, and recoverability under high temperature and high pressure, which is times The appearance is closer to jade white
, the maximum operating temperature is the limit or even up to
, the special R&D and production process ensures the smoothness of the extra-long tanks of special manufacturers (such as), which can be customized in microwave digestion instruments of various manufacturers and specifications. The tank is used with the original microwave digestion instrument
. The processing technology is optimized through special finishing to ensure extremely low background value (blank value). The manufacturer's processing technology can also affect your experimental results
. For imports The inner tank supporting the microwave digestion instrument, especially the inner tank that is widely used
, the processed inner cup can be as good as the experimental data of the general product of the instrument and that of the original import
, and is provided for use with various types of microwave digestion instruments The inner tank is made of all materials and the lid is made of transparent material. The tube body and gasket are all made of natural materials and all materials are available for customers to choose
. We are the only company that can customize the inner tank that comes standard with each manufacturer's instruments. At the same time, we are committed to product quality and originality. Factory consistency has the best price/performance ratio.
Advantages and disadvantages of three commonly used methods for sample pretreatment:
Advantages of high-pressure digestion
: safety, low initial investment, simple equipment, easy operation, less sample and reagent consumption, low blank value, Avoid contamination, sample processing is safe and thorough, 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< br/>: Low investment, simple equipment, easy operation, large amount of reagents, average accuracy, short working cycle, and can process large batches of samples
Limitations
: easy to stain, pollute the environment, and damage the operation Personnel health, poor precision, slightly more reagents, limitations for some insoluble samples
Advantages of microwave digestion
: safety, temperature and pressure control, high efficiency in small batches, samples and reagents Less dosage, low blank value, avoid contamination, high accuracy, high degree of intelligence
Limitations
: Large investment in the early and late stages, high requirements for operators, limitations for certain samples, and Large loss, incomplete digestion, low working temperature, and inability to achieve maximum temperature and pressure at the same time
