Got my first independent third-party analysis back and I'd love a second pair of eyes on how I'm reading it. Main peak area percent looks high, mass-spec identity matches the expected mass, and there are a couple of small named impurities.
Am I right that I check identity first, then purity, then the impurity list — and that the batch number on the report should match the vial? First-report nerves, basically.
Great first-report instincts, Asha — and yes, your order is right: identity (mass) first, then purity area-percent, then the named impurities, with the batch number matching the vial before any of it counts. Dropping this in COA so the analytical regulars can add detail.
Add one habit: glance at the main-peak shape and the baseline, not just the number. A clean symmetric peak on a flat baseline backs up a high area-percent; a high number on a noisy drifting baseline deserves a second look.
This is exactly the reassurance I needed — identity, purity, impurities, batch match. Nerves downgraded to mild caution. Thank you both.
