Ezchrom vs CDS 2.4 areas

We are transiting from openlab ezchrom to openlab cds 2.4. When running the same sample on the same GC using both programs, we see different areas for each compounds. The concentrations are correct because it is a weight % report but why are we seeing much lower areas on cds?


Also, on cds: we need much lower signal events. Normally in ezchrom, we use width of 0.05, threshold of 750 and area of 500. To see the same peaks in cds, we use a width of 0.05, threshold of 50 and area of 50. Why is there such a difference?
