In DLS analysis by Malvern nano-ZS. I got statistical data for Intensity and Volume percentage But no data for Correlation function. How can I use Intensity vs size and Volme% vs Size data for plotting Correlation function. I am asking this because I want present all graph in one window and want to use data fitting. is there any option in software to get correlation data.
Hi,
I have no experience in DLS analysis, but in the case of Intensity being related to Volme% without considering size and, Volme% being related to Size without considering Intensity, I woul use two different plot. Because in this case we have two different relationships.
It is not clear if your file has some problems and you cannot have the correlation data. If it is not so, you can easily extract the correlation data and correlation delay times to report them in a "personal" graph.
Yes, the software can plot the correlation function, and it is also very easy to export the data if you want to do your own fitting. If you have obtained a valid distribution result, then there must also be correlation data, because the correlation function is the raw data from which the distribution is then calculated . The link below has detailed instructions in the last section "How to export to Excel" that might be of use.
