Why do the columns in a chromatograph age?
Thread Content
Currently, with many chromatographs, the colorimetric columns tend to age easily after being in use for a long time
Due to temperature, the properties of a sample are related to its polarity; generally, lower temperatures result in weaker polarity and lower purity, all of which accelerate aging
The meaning of LZ isn’t entirely clear; we can only make an inference based on common sense. Perhaps LZ is asking when the chromatography column should be aged?
I don’t understand what the original poster is talking about: Column aging is necessary; there’s nothing easy or difficult about it.

When samples pass through the chromatography column, some waste is inevitably left behind; once this waste accumulates, it needs to be activated； 2. The sample is too dirty and has become trash; it’s impossible to get rid of it ； 3. The control is not precise; when it exceeds the operating conditions of the chromatography column filler, the contents within the column are lost ； Ultimately, replacing the chromatography column becomes your option
Analytical samples contain many particles, making contamination likely. Then it is aged to restore its performance. Also: This post is only visible to the owner – what’s the point?
There are too many issues; perhaps the substances being analyzed tend to get clogged easily. Proper preprocessing is essential, and the columns as well need to be chosen appropriately. Contact several column manufacturers – they have experience with applications in this industry. Of course, if you use a large quantity, they will provide on-site service.
