[Lab] WXT BPC — PeptideMeter came back 97.2% against a claimed 97.0%
Short version of the title, which is already short: WXT BPC — PeptideMeter came back 97.2% against a claimed 97.0%. Longer version underneath. Numbers, in the order they matter: 97.2% and 97.0%. How to build a series that means something, if you are going to spend money on testing anyway. Three tests on one lot tells…
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.

That service reports area percent by default. Worth stating, since the thread has been comparing it to a mass figure.
post the claim next to the result or the number floats
if you are going to test, test the thing you actually received
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.
