Report to calculate RRT and rank

Andy

Apologies I think I may have confused things more,

I merely meant to say that our reference is its own injection at the start of the sequence (we also run it intermittently through the sequence) however I just meant to clarify that the reference was not mixed with a sample in that first injection, but on its own.

So a second table, filtering using Sample_Name, save the retention time as a variable, apply it to the other table in the report and use a custom calculation?

Is there anything I could do to clarify the situation from your end?

Thank you very much,

Toby

I think that sounds like you're on the right track.

Can you explain to me how you want to report the data for each of the samples?  Are there multiple peaks in the samples?

I'm creating an example results set from the Agilent-supplied example data and I'll build a report and share screenshots with you, to illustrate how I would go about this.

Would that help?

That would be a massive help, please let me know what I could do to thank you!

So there are multiple peaks in a sample but we only quote the RT of the monomer, the other peaks are aggregate and fragments so we quote their percentages but not the RT.

So we would have a report table that has every sample as another row, with columns such as sample name, % HMWS, % LMWS, % Monomer, RT of monomer etc, however we'd also add an RRT of the monomer, relative to the standard. Happy to send a blanked screenshot if it would help.

Thanks again,

Toby

I'm not sure how you're calculating the % HMWS, % LMWS, % Monomer.  Are you identifying 3 "Compounds" in your processing method?

A screenshot would be very useful, I think!
