[Janoshik] JEEP reta 10mg — 98.9%, and yes i paid for it myself
JEEP reta 10mg — 98.9%, and yes i paid for it myself. That is the headline. The document, the batch and the service are below so you can argue with the method rather than with me. Numbers, in the order they matter: 10mg and 98.9%. Inter-lab variance on this assay runs roughly a point either way, driven mostly by…
Agreed on quoting the claim alongside the result. Half the arguments here are two people comparing to different reference numbers.
On inter-lab disagreement, which generates more heat here than anything else.
Two services running different gradients, integrating differently, at possibly different wavelengths, will not produce identical numbers on the same material. A point either way is ordinary. Half a point is close agreement.
The productive response to a gap that size is to post both results with both methods and let the log accumulate. The unproductive response is to pick the lower number, call it the truth, and open a dispute. Members have done the first for long enough now that the bands in the vendor tables are genuinely informative.
Batch number and date of analysis?
Area percent or net peptide content?
results without method are gossip with decimals
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.
Careful with the trend claim. Four results over two years is a very sparse series to draw a line through.
