Digestion tank
1. Introduction:
Nanjing Ruinike Technology’s special high-pressure digestion tank for harmful element detection is also called High-pressure digestion tank, sample dissolver, pressure-dissolving bomb, stuffy tank, digestion tank, PTFE high-pressure tank. --(Wen Li-) The digestion tanks of our unit have solved the problems of customers with large quantity, high requirements, small size and difficult digestion in the digestion process.
Due to the progress of national food safety work dynamics and risk monitoring, a comprehensive analysis of the formulation principles, quality control measures, data analysis, existing problems, etc. of the food safety risk monitoring plan was made from the national level and how to strengthen food safety risk monitoring. Quality control and improving the monitoring sensitivity of problematic foods have put forward relevant requirements. Therefore, our company has launched a high-pressure digestion tank to solve the problem of sample digestion.
The high-pressure digestion tank dedicated for hazardous element detection can reach a temperature of ℃ withstanding pressure in the oven
.
The inner cup is made of experimental-grade high-purity polytetrafluoroethylene. The blank value of metal elements is low, and the content of lead and uranium is less than 100%. No dissolution and precipitation, no added return materials, and extremely low background. The outer tank is made of national standard stainless steel, and the inner cup can also be matched. Acid-catching device
In the later stage, do acid-catching and digestion experiments. 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, Chinese Academy of Sciences Beijing The Institute of Botany, Nanjing Soil Research Institute of the Chinese Academy of Sciences, Shanghai Ceramic Institute of the Chinese Academy of Sciences, Nanjing University, Qingdao CET, Beijing CET, Shanghai CET, etc. have received very good feedback.
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. Features of the high-pressure digestion tank dedicated for harmful element detection:
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 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)
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.

3. Working principle:
/> Special high-pressure digestion tank for harmful element detection: The use of 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 reduce the volatilization loss of the measured components. Minimizing it 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.
The high-pressure digestion method is recognized as a standard method by relevant departments in my country, such as,,,,,/,/-, etc. The United States also stipulates that this method is the standard decomposition method of samples for the determination of elements such as , , , , , and .
Our company’s domestically exclusively developed
Imported polytetrafluoroethylene
Inner cup
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
