1. Introduction:
Nanjing Ruinike high-pressure digestion tank is also called autoclave, pressure digestion tank, pressure dissolved bomb, stuffy tank, digestion tank, polytetrafluoroethylene high pressure Can. -- (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.
Metal detection for food safety risk monitoring has attracted increasing attention in daily life, such as: rice, wheat, barley, soybeans, corn, various oils, various grains, rice, wheat flour, various edible oils, some industries Oils, noodles, instant noodles, soy sauce, vinegar, etc. contain harmful heavy metal pollution elements, pesticide residues, fatty acids and trans fatty acids and other elements that are harmful to our health. In order to ensure the quality and safety of finished grains and oils, a certain city has continuously increased monitoring efforts. The number of batches of finished grains and oils monitored every year is three times that of the previous year.
The temperature of the high-pressure digestion tank in the oven can reach ℃ withstand pressure. The inner cup is made of polytetrafluoroethylene and has a low blank value of metal elements. The content of lead and uranium is less than 100%. No dissolution and precipitation, no recycled materials added, and extremely low background. The outer tank is made of national standard stainless steel. Moreover, the inner cup can also be used with the acid-catching electric hot plate of our unit for later use in acid-catching and digestion. Such as: Taiyuan City, Shanxi Province D, Xinzhou City, Shanxi Province D, Zhongshan City, Guangdong Province D, Nanshan District, Shenzhen City, Guangdong Province D, Nanning City, Guangxi Province D, Beihai City, Guangxi Province D, Guangxi Zhuang Autonomous Region Food and Drug Inspection Institute, etc. Feedback The effect is excellent. 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.
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.
Our company’s domestically exclusively developed
Imported polytetrafluoroethylene
Inner cup
3. Features of the high-pressure digestion tank:
Good sealing: the inner cup of the high-pressure digestion tank The concave and convex tongue and groove design of the cup and the pointed bottom design of the inner cup cover 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 blank value of elements in the inner cup improves the accuracy and precision of analysis and reduces work intensity and environmental pollution
. The sequential numbering of the inner cup/outer tank facilitates 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)
The background that is more resistant to penetration and deformation ensures a 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.
Material of the inner cup of the microwave digestion tank
Characteristics:
The inner tank is made of high-purity experimental grade imported enhanced modified materials
Compared with: In addition to all the advantages of It has some improved characteristics: it has a lower background to ensure better resistance to deformation, penetration resistance and recoverability under high temperature and pressure, and its appearance is closer to jade white
, and the maximum use temperature is the limit or even up to
, Special R&D and production technology ensures the smoothness of the extra-long cans of special manufacturers (such as). The inner tank of the microwave digestion instrument of various specifications from each manufacturer can be customized to be used with the original microwave digestion instrument
. The processing technology is optimized through special process finishing. Ensure extremely low background value (blank value). The manufacturer's processing technology can also affect your experimental results
, for the inner tank supporting the imported microwave digestion instrument, especially the widely used inner tank
, processing The inner cup of the instrument can be as good as the experimental data of the general product and the original import
. The inner tanks used in supporting various types of microwave digestion instruments are all made of materials, the lid is made of transparent material, the tube body and the gasket are all made of the same material. 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 promise that the product quality is consistent with the original factory and has the highest price/performance ratio.
