13 terms shown. The filter works only on the definitions published on this page.
- Acceptance limit
- A stated criterion against which an analytical result may be compared in a controlled testing context. A label or document alone does not show whether a limit is appropriate, applicable, or independently confirmed.
- Analytical procedure
- The documented method used to generate a measurement, identification, separation, or other test output. Its suitability depends on its intended purpose and validation context.
- Batch or lot
- An identifier used to associate material with a production or documentation record. A matching number on a public file does not by itself authenticate the material, document, laboratory, or chain of custody.
- Certificate of analysis (COA)
- A document that may list tests, methods, specifications, and reported results for a named material or batch. This glossary treats a COA as document context, not a quality certification or product recommendation.
- Chromatogram
- A visual output from a chromatography procedure showing detector response over time or another separation dimension. Reading a chromatogram requires method-specific context that may not be present in a public image or document.
- High-performance liquid chromatography (HPLC)
- A family of separation methods used in analytical research and laboratory work. In peptide research, chromatography can separate or characterize material; a method label alone does not establish identity, purity, quality, or suitability.
- Identity
- A testing question about whether a sample is consistent with the material it is represented to be. An identity statement should be read with the stated method, result, scope, and source context.
- Impurity
- A component other than the intended analyte that may be considered in an analytical procedure. Whether an observed signal is measured, identified, quantified, or relevant depends on the procedure and its stated scope.
- Mass spectrometry (MS)
- An analytical technique that measures ions according to mass-to-charge behavior. It can contribute to molecular-characterization work, but a reference to MS does not independently validate a public document or a material claim.
- Method validation
- A process used to establish whether an analytical procedure is suitable for its stated intended purpose. Peptide Index does not validate analytical methods, laboratories, reports, or products.
- Result
- The value, observation, or statement reported by a procedure. A result should be kept with its method, units where applicable, acceptance context, date, and source; it is not a standalone conclusion.
- Specification
- A set of stated criteria for a material, procedure, or result in a documented quality context. A public specification does not establish that a specific material met it or that the context applies to a particular visitor.
- Stability or retest context
- Documentation related to how a material is monitored or revisited over time in a controlled setting. It should not be converted into personal storage, product-life, or use guidance.
