LOT-SPECIFIC QUALITY CONTROL

Evidence belongs
to the batch.

A product image identifies the format. Quality conclusions require linked analytical records for the exact production lot.

THREE COMPLEMENTARY LAYERS

No single file tells the whole story.

COA, chromatography and mass spectrometry answer different questions. Confidence comes from matching the method, result and lot identifier across the document set.

01

COA / LOT RECORD

Certificate of Analysis

The result index for a specific lot: product identification, test list, specifications, actual results, dates and approval status.

  • Lot and sample identification
  • Result compared with specification
  • Method reference and authorization
ANSWERSWhat was tested and did it meet the stated specification?
02

HPLC / CHROMATOGRAPHY

Chromatographic profile

A separation profile used to assess the principal component and related peaks under a defined analytical method.

  • Main peak and relative peak areas
  • Retention-time context
  • Method, column and detection conditions
ANSWERSHow did the sample separate under the stated conditions?
03

MS / MASS SPECTROMETRY

Molecular-mass signal

A mass-to-charge spectrum that supports molecular identity when the observed signal is interpreted against the expected analyte and method.

  • Observed mass-to-charge signals
  • Expected molecular-mass comparison
  • Instrument and interpretation context
ANSWERSIs the expected molecular-mass signal present?

CONTEXT BEFORE PERCENTAGE

A number without a method is incomplete.

A reported area percentage should be read together with the chromatogram, sample preparation, reference material, system suitability and analytical conditions. HPLC does not establish molecular identity by itself.

01
Check the method

Column, mobile phase, detector and calculation approach.

02
Check traceability

The same lot identifier across the COA, chromatogram and spectrum.

03
Check specification

The actual result must be evaluated against a stated acceptance criterion.

BATCH TRACEABILITY

One lot. One linked evidence trail.

The documentation chain should allow a reviewer to connect the tested sample, analytical records and released format without mixing data from different lots.

01Lot assigned

A unique production identifier is created.

02Sample recorded

The analytical sample is linked to that lot.

03Methods performed

Results are generated under defined procedures.

04Records reviewed

Results and specifications are checked together.

05Document set linked

COA, HPLC and MS remain associated with the lot.

TRANSPARENT INTERPRETATION

What the records show — and what they do not.

The document set can support

  • Lot-specific test results
  • Chromatographic profile under the stated method
  • Presence of the expected molecular-mass signal
  • Comparison with documented specifications
×

The document set cannot replace

  • Verification of storage and handling after release
  • Independent sampling when chain of custody is unknown
  • Clinical safety or suitability for human use
  • Regulatory registration or medical authorization
