Hi!
I want to check whether this peak indicates contamination of the column or contamination of the autosampler.
I have a peak in the chromatogram, the nature of which I do not know. It is present in all samples and in the solvent sample.

Could you suggest how to do the analysis without sample input and how to do it in OpenLab CDS?
I hope for your help.
Thank you all.
