HPLC: separation, detection and analytical results
HPLC names a separation technique; the result depends on the analytical question and specific method.

Separation does not measure everything
High-performance liquid chromatography separates mixture components using mobile and stationary phases. A detector records signals from components to which it responds. HPLC alone does not specify the detector, calibration or assessment criterion used.

What a report should clarify
Look for the sample, column, mobile phase, detector and calculation procedure. For example, percentage peak areas answer a different question from concentration determined using standards. Preserve that distinction when comparing documents, even when both are labeled HPLC.

Questions about this reference
Does HPLC mean sterility was verified?
No. Chromatographic separation is not, by itself, a sterility test.
