Overview of graphite digestion analyzer:
In most metal element analysis processes, the wet sample digestion method is recommended as a sample pretreatment method by inspection agencies and standards due to its advantages of easy operation and low equipment cost. However, the current wet digestion methods mostly use flat plate or water bath electric heating devices, which all have problems such as uneven heating, inaccurate temperature control, low thermal efficiency, and require a large amount of electricity to process a batch of samples. Relatively speaking, the wet digestion device made of graphite material that is lightweight, inert, has fast and uniform heating and thermal conductivity can effectively solve these problems, and is accepted by many inspection institutions for its moderate price, energy saving and environmental protection. It has now become one of the commonly used equipment in laboratories.

Main features of graphite digestion instrument
·Elegant appearance: neat and tidy, with various buttons arranged reasonably and neatly.
·Clean and corrosion-resistant: The heating body of the room temperature digester is coated with a thick PFA coating, which is corrosion-resistant and pollution-free. Adopting a unique spraying process, the coating is uniform, firm, and will not peel off even after long-term use. The heating element and tabletop of the high-temperature digestion instrument are made of graphite with thermal conductivity, high temperature resistance, and corrosion resistance. The control box adopts anti-corrosion switches, which can be used with confidence in corrosive environments such as strong acids and alkalis.
·Adopting an integrated surrounding heating method, all parts of the sample are uniformly heated, which greatly prevents heat loss and eliminates temperature differences between different parts of the same sample, resulting in rapid digestion.
·Temperature control: PID temperature control system, easy to operate, excellent performance, and durable. High temperature control accuracy, up to ± 0.2 ℃, adjustable heating rate, program heating and controlled heating holding time, stable heating rate, high and low temperature alarm, automatic heating stop
Traditional electric heating sleeves, electric furnaces, etc. can only locally heat the sample container, resulting in uneven heating of the sample and temperature differences between different parts of the sample. In addition, the open heating method causes significant heat loss, leading to a large gap between the sample temperature and the surface temperature of the heater.
·More economical: Traditional thermal digestion samples usually take several hours, and difficult to digest samples can even take several days, consuming a lot of electricity; The surrounding heating process is fast, convenient, can save 75% of electricity, and has low operating costs.

·Thermal conductivity: A reasonable heating method matched with a heating element with thermal conductivity can ensure temperature uniformity between each digestion well, with a temperature difference between samples of less than ± 1.5 ℃ (room temperature -210 ℃). When digesting multiple samples, it can ensure the same reaction temperature and conditions for batch processing.

Efficient heating method for graphite: The integrated surrounding heating method using graphite material ensures uniform heating of all parts of the sample. The surrounding heating method largely prevents heat loss and eliminates temperature differences between different parts of the same sample, resulting in rapid digestion.
2. The overall anti-corrosion of the graphite digestion instrument: It is processed and developed using different anti-corrosion materials, which are not afraid of corrosion both inside and outside the body, greatly extending the service life of the equipment.
3. Accurate temperature control: The PID temperature control system is easy to operate, has excellent performance, and is durable. High temperature control accuracy, up to ± 0.2 ℃, adjustable heating rate, program heating and controlled heating holding time, stable heating rate, high and low temperature alarm, automatic heating stop.
4.

When digesting multiple samples, it can ensure the same reaction temperature and conditions for batch processing.
Overall, the graphite digestion instrument has a large heating area and a relatively balanced temperature. The electric heating plate only heats the bottom, and the temperature is prone to unevenness. The graphite digestion instrument can accept large-scale sample processing. In terms of service life, graphite digestion equipment is also longer than electric heating plates. Graphite digestion instruments now use remote control experiments, which can keep the human body away from the heating element and make overall operation more convenient; Most electric heating plates cannot achieve this function.
