Why are there three graphs and then a fourth?
The sample moved through the column once. The instruments watched that same run in three ways, then opened the mass pattern from selected scans.

How much should I rely on this explanation?
This page translates the signed COA; it does not retest the sample. The laboratory made the identity, purity, and quantity determinations. This preview explains those reported results without asking you to interpret instrument settings or calculate molecular ions.
What do the MS numbers mean?
The instrument gives molecules an electrical charge, then measures their mass relative to that charge, called m/z. Numbers above the peaks are those measurements, not purity percentages or milligrams.
How does that help identify my compound?
Expected mass → Measured signals → Lab's identity conclusion
The chemical formula tells the lab what mass signals to expect. The lab compares the measured pattern with that expectation to assess identity. A single number alone does not prove the complete molecular structure.
Why more than one peak? One molecule can produce several signals. As a simplified example, a molecule with mass near 1,000 can appear near 1,000 with one charge and near 500 with two charges. It has not been cut in half. Actual readings also depend on how the charged ion forms.
Other peaks can reflect different charges, isotopes, attached ions, fragments, background, or other substances. They are not automatically impurities. The lab's individual peak assignments are needed to say exactly what each represents.
This guide explains the laboratory's reported conclusion. It does not independently verify identity or assign unconfirmed peaks.
