How We Verify Every Batch

Two complementary tests confirm what is in the vial: HPLC measures how pure it is, and mass spectrometry confirms what it is.

HPLC ChromatogramIllustrative example
Main peak minor Retention time (min) Absorbance

Purity is calculated from the area of the main peak compared with all peaks.

Mass SpectrumIllustrative example
[M+H]⁺ [M+2H]²⁺ Mass-to-charge ratio (m/z) Intensity

The dominant ion peak is matched against the expected molecular weight.
