Hi,

I am using a multipoint calibration curve and am looking for a way to make Chemstation process the %RSD (for peak area) and mean % deviation for each level of standard instead of processing all the levels of standards together. I would like this to process as part of the summary report, but if I have to do another report that would work as well.

Thanks in advance.

I suppose the way I would do this is to process each point separately using "evaluate data file as continuing cal.." under the concal menu, just set continuing calibration criteria each time first.

I don't think there is a way to do this as part of normal ChemStation reporting. You could try reprocessing the sequence, and only reprocess each standard. Using the Sequence Output reports you could then get statistics for each set.

The easier option would be to export to Excel and do the calcs there.

Thanks for the replies. I will most likely stick with excel since it will take just as long to reprocess. ;/

If you don't have it, there are macros that can automatically transfer the data.
