Summary of lab dupes and spikes

Hi , I was just wondering if there is a way to use ESdat to provide a summary of laboratory internal duplicates and spikes which includes: · Number of pairs; · Ranges of the RPD% for duplicates (e.g. 0 to 50%) and the % recovery for the Spikes (75 to 125%); and · And the number of exceedances outside of the acceptable range e.g. 50% for duplicate RPD% and ±25% for spike samples.

Yes it is reported, · Number of pairs of duplicates and spikes; Given in "Count of Samples", and also in the optional "Summary By Compound" table. · Ranges of the RPD% for duplicates for the Spikes Given by compound under "Summary By Compound", not given across all compounds but you can easily get that from the Summary By Compound table. · And the number of exceedances outside of the acceptable range These are given in the table of contents ie "Lab Duplicates with high RPD's (4)" The "Summary By Compound" table is only produced if selected prior to report generation. It is at the bottom of the Output to Excel tab.

The ESdat QA Report doesn't summarise that kind of information for the "Secondary Laboraotory", ie that used for the Interlab Duplicate. However, you can see the samples for any particular lab report by viewing the Samples for that lab report under Chem Tracking - Chemistry Samples, Results can be seen under "Chem Tracking - ....Raw Results", filtering for spikes, etc.. as appropiate.
