Understanding HPLC Purity Analysis
High-Performance Liquid Chromatography (HPLC) separates the components of a sample so the main compound can be measured against any impurities. The result is a purity percentage — for example, ≥98% — that reflects how much of the sample is the target compound.
Purity vs. identity
Purity and identity are two different questions. HPLC answers 'how much of the sample is the compound?' Mass spectrometry answers 'is it the right compound?' by confirming molecular mass. Strong documentation addresses both — a purity value and an identity confirmation.
Why measured beats claimed
Any listing can print a number. A measured value, backed by a batch-specific COA that names the method, is evidence. When comparing suppliers, weigh the documentation behind the figure — not just the figure itself.
