Average Blank Subtraction as Opposed to most recent blank in CDS 2.6 custom calculation

Hello,

Are you trying to do this in IR or custom calculator? In IR you would need to create a table or field filtered by sample type 5, and then store the peak area as an indexed aggregator by compound name. You could then use the average of the aggregator to do your calculation in subsequent tables. You can hide the first table so it does not show on the report. The other option would be to do the calculation in CC and then report or use the CC value in your IR report.

Hello,

Also this would only allow you to use the blank values for reporting calculations. If you are trying to subtract the raw data of the blank from the other injection there is no way to do this the software will only use one blank file. This is the only way for the blank to effect say the calibration curve.

It's all done under reporting. How do you hide tables in the report though? I have been designing report templates(from Agilent's initial templates) based on my employer's specifications and it has been difficult to make an equation that would work for an average blank subtraction for true compound concentration.  I will try your suggestion and get back to you though. Thanks

Hide tables in the Advanced settings for the table.  There's a checkbox for "Visible".
