Agreement across two services is much stronger. A single high number does not…
Coming back to: Lateral-flow and colorimetric approaches: the specificity problem Replied, post #88 · Analytics › Home & field testing · 26 Jul 2026 · 5 likes Worth separating two things that post #84 runs together. Lateral-flow devices: like a rapid COVID test. They have a reagent strip and produce a colour result. They are…
What a reversed-phase purity number actually is Replied, post #94 · Analytics › HPLC & UHPLC · 26 Jul 2026 · 0 likes Worth separating two things that post #90 runs together. Before anything else: what was the gradient, and at what wavelength? Area percent at different wavelengths is…

Here for the analytics and not much else Replied, post #8 · Lounge › Introductions · 8 Jul 2026 · 6 likes Lurking first: if you want to introduce yourself after lurking a bit, that is fine. You do not have to introduce yourself before your first technical post either.
