Causes of the failure to increase temperature in the column chamber
Thread Content
What are the causes of the issue where the column chamber does not heat up? Thank you all for sharing your opinions! :)
Check the settings for the heating area and verify the temperature settings. Make sure that the confirm button was pressed after making the adjustments. There are generally two possibilities: 1) The instructions were not transmitted; 2) Even if they were transmitted, the function of the heating area is damaged. Another possibility is a communication issue
Hardware: It might be that the heating module is damaged, or there is a problem with the temperature sensor. Or there might be a chain mechanism; some area isn’t set up to prevent temperature rise. Software: Not properly set up, or not determined yet. Actually, it’s pretty much the same as what was said above. It is recommended to list the brand and model of the instrument, as different instruments may have different causes. Only in this way can it be solved better.
It’s likely that the heating element is broken, or the power supply for heating has been disconnected. What brand is your chromatograph?
There are roughly three reasons: 1. The heating button or command has not been issued, so no heating occurs； 2. Poor contact or damage to the heating circuit board ； 3. The heating wire is broken, so it cannot heat.
