Understanding HPLC
Summary
High-performance liquid chromatography separates the components of a sample. Here is how a chromatogram is read and what it can and cannot tell you.
Key concepts
- Stationary and mobile phase
- Retention time
- Peak area
- Method dependence
Research context
HPLC results are frequently reported as a percentage based on relative peak area. That figure is only meaningful alongside the method, detector and reference standard used.
Evidence type
Review. Evidence labels are navigational aids. Preclinical findings do not establish human safety or efficacy.
Limitations
HPLC alone does not confirm molecular identity; it is often paired with mass spectrometry.

Understanding Mass Spectrometry
Mass spectrometry measures mass-to-charge ratios. It is a common way to check whether observed mass is consistent with an expected molecule.
