Testing & Documentation
What each test verifies
Identity / Mass
Confirms the material in the vial is the intended compound and that its molecular mass matches the expected value (typically by mass spectrometry). Verifying identity means you are working with the correct reference material — not a mislabeled or substituted one.
Purity (HPLC)
High-performance liquid chromatography separates a sample into its components and can quantify a target compound relative to impurities. Any reported result applies only to the sample and report that identify it.
Sterility
Screens the lot for microbial contamination. A sterile reference material reduces a source of variability and interference in laboratory work, keeping your handling conditions controlled.
Heavy Metals
Measures trace heavy-metal content against defined thresholds. Low heavy-metal levels remove a common inorganic contaminant that can interfere with analytical measurements.
