What HPLC reports
Reversed-phase HPLC separates detected components under a defined column, mobile phase and gradient. The chromatogram supports a relative purity calculation under those conditions.
What LC-MS reports
LC-MS combines chromatographic separation with mass measurement. Observed mass can be compared with the theoretical value while considering charge states and instrument tolerance.
Why both matter
A clean chromatogram and an expected mass answer different questions. Review the raw plots, stated method and numerical results rather than relying on a single summary word.
