There are some common problems that may be encountered during the use of graphite digestion instrument:
Uneven heating or inaccurate temperature: This can be caused by a damaged heating element or a faulty sensor. At this point, the connection between the heating element and the sensor should be checked and confirmed if they need to be replaced or calibrated.
Bubbles: may be caused by poor sealing or improper handling. In this case, it is necessary to check whether the seal is in good condition, ensure a tight seal, and pay attention to the operating specifications to avoid excessive sample volume or excessive heating temperature.
The instrument does not start or does not work properly: It may be caused by a power failure or a malfunction of the control system. At this time, you should check whether the power cord is loose or damaged, and make sure that the power supply is stable. If the problem persists, you may need to contact after-sales service for repairs or replacement of control system parts.
In addition, there are some other problems that may be encountered during the use of the graphite digestion instrument, such as incomplete digestion and resuction of the digestion solution. These problems can be caused by improper handling, inaccurate reagent concentration, instrument failure, etc.
To solve the above problems, you can take the following solutions:
For uneven heating or inaccurate temperatures, the connection between the heating element and the sensor can be checked to see if it needs to be replaced or calibrated. At the same time, the heating power and time can be adjusted to ensure that the sample can be fully digested.
For problems with air bubbles, you can check that the seals are intact to ensure a tight seal. At the same time, pay attention to the operation specifications to avoid excessive sample volume or high heating temperature.
For the problem that the instrument does not start or does not work properly, you can check whether the power cord is loose or damaged, and make sure that the power supply is stable. If the problem persists, you may need to contact after-sales service for repairs or replacement of control system parts.
For incomplete digestion, parameters such as digestion time, temperature, and power can be adjusted to ensure that the sample can be fully digested. At the same time, pay attention to whether the concentration and purity of the reagent meet the requirements.
For the problem of digestion fluid suction, you can check whether the tightness of the instrument and the cooling system are working properly. At the same time, pay attention to the operation specifications to avoid the suction of the digestion solution.
In short, when using a graphite digester, the operator should be familiar with the solutions to common problems and operate in strict accordance with the operating procedures. When encountering a problem, you should calmly analyze the cause and take appropriate measures to solve it.
