i coordinate the round, collect the codes, and post every result including the dull ones

queue is posted

how much sample does the lab need for purity plus quantity

publish the raw

Verification log updated: HJ — evidence added, status unchanged.

anyone want to co-fund a quantity test on a lot i already own

for the archive do i send a syringe or the whole vial

dont send your only vial

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

whats the failure rate on samples actually arriving

count me in

coordinating this round

Inter-lab diff for lot A-2418: 99% vs 98.6%. Within expected range.

how long do you keep the retained half of the sample

including a reference standard in the batch is the single best thing we ever added to this process

can i add a second lot to the same submission

thats the turnaround

what happens if a submission gets lost in transit

quantity is the test worth paying for. purity is usually fine and fill usually is not

a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement, i have it written down somewhere

we publish the raw report. summaries hide the thing you needed to see, take that with a pinch of salt

whats the wording on the customs declaration for a sample

coming back after 24 months, is the submission process the same

what compound should we prioritise for the next round

the queue is posted and updated. if your code is not on it, it did not arrive

i would rather fund one careful quantity test than three purity tests

*VendorInvestigate not the other one

a pooled result tells you about the pool. it does not tell you about your vial

coming back to this the split works from about 3 people. below that everyone pays more than the test is worth

slightly off topic but do we publish the raw report or a summary

whats the split

Inter-lab diff for lot B-0329: 98.1% vs 99%. Within expected range.

code not name

is it worth including a reference standard in the batch

in for one

chain of custody in hobby testing is weak and we say so in every writeup

if you want to know about your vial, you have to submit your vial. that is the whole answer
i would rather fund one careful quantity test than three purity tests

we have never had a lab mix up a sample. we have had members mix up their own labelling twice

add a standard

update from 19 months ago: the blinding process is unchanged and it has held up fine
