01 · Product identity
Confirm that the product name, molecular form, sequence or composition, and batch identifier agree across the vial, catalog record and source report.
Quality assurance
How We Approach Verification
Trust is earned through verifiable data, not marketing claims. Explore the standards used to evaluate identity, purity, supporting methods, and complete batch traceability.
02 · Issuer traceability
A credible report identifies the issuing organization, report or sample identifier, dates, methods and authorization. A logo or generic result table alone is not enough.
03 · Method suitability
Review whether each analytical method is suitable for the stated question and whether its conditions, acceptance criteria and limitations are documented.
04 · Measured results
Distinguish actual measured values from catalog specifications. Every result shown online should map faithfully to an authentic source record.
05 · Release decision
If a supplier represents a batch as released, the source documentation should show the relevant acceptance criteria and who authorized the decision.
06 · Publication integrity
Publish the original report or a verifiable copy without inventing missing fields. If documentation is unavailable, mark it pending rather than creating sample values.
Methods
What common methods can measure
Reverse-phase HPLC — purity profile
Chromatographic separation with UV detection can estimate the relative peak-area profile under stated conditions. Interpretation requires the chromatogram, integration method and method limitations; it does not establish identity by itself.
LC-MS — identity support
Mass spectrometry can compare measured ions with the expected molecular mass. The report should state ionization mode, observed values and the basis for interpretation.
Karl Fischer titration — water content
Karl Fischer analysis measures water content, which can affect mass calculations. A useful record identifies the method and measured value rather than presenting a generic catalog estimate.
LAL — bacterial endotoxin
LAL methods can quantify endotoxin under defined conditions. Results should be interpreted with the method, units, controls and sample preparation described in the source report.
ICP-MS — elemental analysis
ICP-MS can screen for selected elements. A complete record states the analytes, reporting limits, preparation method and actual measured results.
Documentation before claims.
Published analyses link to the issuing laboratory's own verification page, so you read the measured results at the source. Products without a report stay marked as pending.
