Understanding the HPLC specification.
HPLC is the stated analytical method for the current 98% product specifications. Method details and product- or batch-specific evidence must be confirmed separately.

Specification versus batch result
A specification describes a stated product requirement. A batch result records a measurement for particular material. A 98% HPLC product listing is not evidence of an actual batch measurement.
Method details matter
Send focused analytical questions with your technical inquiry. These questions help identify the records your laboratory needs; they are not a published test method or a statement that a particular batch was tested.
- Which method reference and version apply to the material under review?
- Is the reported percentage an assay value, peak-area percentage or another reporting basis?
- How are the sample identifier, product identity and batch reference connected in the report?
- Can the applicable chromatogram, integration details and analytical conditions be provided for review?
Equipment evidence boundary
The HPLC workstation shown is real equipment from our affiliated manufacturing company. It supports analytical capability but does not establish that a specific Tetrandrine or Cytisine batch was tested.
Request the applicable evidence
Use a Technical Information request for method or interpretation questions, or request the applicable COA for batch review. No product-specific chromatogram or method is published here.
