Why the distinction matters
A chromatographic purity statement and an amount or content statement describe different measurements. They should not be treated as interchangeable labels or converted by assumption. A result needs the context provided by its actual report.
Use percentages carefully
Terms such as high purity peptides China and 98% pure peptides China appear in procurement searches, but a search phrase is not evidence of a batch result. The website therefore leaves numerical claims to the relevant specification and document.
Define the review question
Ask which attribute your institution needs to assess and which document addresses it. This keeps the discussion focused on the relevant evidence without turning a general marketing number into an unsupported guarantee.
