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 manufacturing period. A two-year-old result is evidence about two years ago and should be read that way.
Chain of custody is why member-funded testing is worth more than a supplied certificate: the vial tested is the vial that arrived at a member’s door.
If somebody has the same thing measured a different way, post it next to mine and we will see whether they agree.
best — the order this archive was captured in
Area percent and net peptide content are different measurements and most reports give one. Quote which, or the comparison downstream is meaningless.
What a result posted here is actually worth, and how to make yours worth more.
A single figure with no batch identifier is about a vial nobody can locate. Add the batch and it becomes about a lot. Add the claimed figure from the certificate and it becomes a comparison. Add the service and the date and it becomes reproducible. Say that you paid for it yourself and it becomes independent.
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.
The template is vendor, compound, batch, service, claim, result, and who paid. Every one of those fields exists because a result missing it has been argued about here before.
The template is vendor, compound, batch, service, claim, result, and who paid.
Disagreeing with this line: that gap is ordinary variance, not a contradiction between the lab and the certificate.
the trend across lots is worth more than any single figure
Batch number and date of analysis?
Which service, and did you pay for it yourself?
Careful with the trend claim. Four results over two years is a very sparse series to draw a line through.
I would not post that as a finding. It is a single result and the template asks you to say so.
