genuine question send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it

Highlights from this day
- LC_MS_Lena — i keep half the sample back so there is something to send if the first one goes missing, i have it written down somewhere 17:18
- taper_tess — a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement, for what its worth 17:21
- LC_MS_Lena — while im here VendorInvestigate has been the fastest for us. Medutest has been the most detailed. those are not the same lab 18:25
count me in
thats the turnaround
declare it as an analytical reference sample with a low value. that is what it is
how many people do we need before the split is worth it
we do not help with wording beyond that and the mods are strict about it
roughly one sample in 5 rounds has gone missing in transit. budget for it emotionally

blinded obviously
i would rather fund one careful quantity test than three purity tests
follow up including a reference standard in the batch is the single best thing we ever added to this process
if you want to know about your vial, you have to submit your vial. that is the whole answer

dont send your only vial
whats the failure rate on samples actually arriving
who is coordinating this round
whats the split
genuine question quantity is the test worth paying for. purity is usually fine and fill usually is not
do you want the vial reconstituted or as powder
