Product Description

Product advantages:

1. It is specially designed for the geological industry, with the advantages of practicality, compactness and sealing. Applied to sample pretreatment of chemical analysis methods such as gas phase, liquid phase, plasma spectrum mass spectrometry (ICP-MS), atomic absorption and atomic fluorescence, used in food, geology, metallurgy, environmental protection, commodity inspection, chemical industry, nuclear engineering and other systems, digestion Pb, Cu, Zn, Fe, Ga, Cr, Rb, Hg, Sn and other heavy metals in pesticide residues, food, rare earth, aquatic products and other organic matter.

2. The closed high temperature and high pressure sample digestion method ensures the complete decomposition of most insoluble minerals and avoids the loss of volatile elements. Since the acid does not volatilize during the sample dissolution process and repeatedly refluxes in the system, only a small amount of high-purity acid is needed to complete the complete decomposition of the sample, thus ensuring a very low value. Since ICP-MS is a rapid analysis technology based on solution sampling, its powerful analysis capability inevitably poses challenges to the sample processing method. The effectiveness of the closed high-temperature and high-pressure digestion of geological samples has greatly promoted the application of ICP-MS in the analysis of geological samples. The main advantage of geological digestion tanks is to overcome the problems of material instability, acid leakage and tank rust.


working principle:

Use the strong acid or strong alkali in the tank and the high temperature and high pressure airtight environment to achieve the purpose of quickly digesting insoluble substances. It is a good assistant for digesting samples when determining trace elements and trace elements. The temperature used in the oven can reach 200°C and the pressure is 5Mpa.


Features:

1. Use in an oven at 200°C-250°C. Safety is fully considered in the design, from passive temperature control to active pressure control. The tank body adopts a circular tongue-and-groove seal design, and the manual screw fastening has good sealing performance, avoiding the loss of volatile elements; there is a vent hole on the top of the cup, which has a high safety factor;

2. We are a manufacturer in the industry that can produce PTFE raw materials by ourselves. We pay as much attention to the background of the material as you do, just to ensure a very low background;

3. Easy to use: the inner cup adopts a special design, which is easy to clean; the inner wall is processed by precision equipment, and the inner wall is smooth and does not hang water;

4. The inner and outer tanks are numbered sequentially without mixing, which facilitates the distinction of samples in the experiment and improves the repeatability of the experiment;

5. It has high digestion efficiency and strong ability, and can digest many samples that are difficult to digest by traditional methods. It has a wide range of applications and can be used to process multiple samples at the same time;

6. It consumes less acid solvent and is specially designed for the geological industry. It has the advantages of practicality, compactness and sealing. It can also be customized according to requirements. The inner cup can be changed to PFA, which is sealed, pressure-resistant, resistant to penetration, and resistant to deformation, which improves the accuracy and accuracy of the analysis, reduces the work intensity and environmental pollution;

7. Complete specifications, can be oriented processing.


Commonly used digestion methods, such as:

Weigh about 50.00mg of rock samples into a polytetrafluoroethylene inner cup, add 1.5ml HNO3, 1.5ml HF and 0.01ml HCIO4 in sequence, steam on a 140°C electric heating plate until wet salt, then add 1.5ml each of HNO3 and HF mL, sealed with a steel jacket, and heated in an oven at 190°C for 48h. After cooling, evaporate to dryness on the electric heating plate, add 3.0mL HNO3 and steam to wet salt, then add 3.0mL50% (V/V) HNO3, add a steel jacket and heat in an oven at 150°C for 12h. After cooling, transfer to a clean PET (polyester) bottle, add Rh internal standard solution and dilute to 80.00g with deionized water, so that the concentration of Rh in the solution is 10ng/ml, and wait for the measurement on the machine.


We can provide sample preprocessing vessels and instruments for the geological elemental analysis industry:

1. Teflon containers——FEP, PFA, PTFE series, storing high-purity reagents

2. Acid purifier, acid distiller - provide high-purity acid and high-purity water for the laboratory

3. Teflon bottle mouth dispenser - specially for pipetting strong acid and alkali, especially HF

4. Geological closed sample dissolution tank - in the high-pressure digestion method, the geological and mineral samples are digested

5. Anti-corrosion electric heating plate, high temperature plate, digester - heating and digestion in the early stage, acid removal treatment in the later stage

6. Acid countercurrent vessel cleaning device - cleaning of Teflon vessels, inner cups of digestion tanks, and microwave tanks
