the test results thing finally clicked for me and I want to write it down
The title is the argument: the test results thing finally clicked for me and I want to write it down. Here is the rest of it. If the report gives a mass spectrum as well as UV purity, say so. Identity and relative quantity are separate claims and the log tracks both. Date of analysis anchors the result to a…

Five extra fields, thirty seconds of typing, and the difference between a comment and a row in the log that will still be useful in three years.
Did the vial lot match the paperwork lot?
results without method are gossip with decimals
area percent unless the report says otherwise
a result with no batch number is about a vial nobody can identify
Correction: that is the claimed figure, and the measured one is the higher of the two in your own screenshot.
Is that the same lot as the one in the thread from last month?
Fourth lot from the same supplier in the log now and the band has been tight the whole way. That consistency is the actual finding.
Kept every report as a PDF with the batch in the filename. Two years in, it is the most useful folder I own.
Right, and a point or two between services is ordinary. It is agreement, and every month somebody posts it as a scandal.
