help me understand below spec, I have read the wiki twice
Question in the title, detail here: help me understand below spec, I have read the wiki twice. 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. Area percent and net peptide content are…
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.
area percent unless the report says otherwise
What was the claim on the certificate you are comparing against?
Disagree that this is a discrepancy. 98.3% against a claimed 97.5% is inside ordinary inter-lab variance in either direction.
Yes. Two services on the same batch is the strongest thing an individual member can produce, and it is not expensive.
a result with no batch number is about a vial nobody can identify
