Frequently Asked Questions
What does HPLC-UV testing measure?
High-Performance Liquid Chromatography with UV detection (HPLC-UV) separates the compound from potential impurities using a liquid mobile phase. The UV detector measures absorbance at a target wavelength, allowing precise quantification of the target compound and any co-eluting species. Purity is expressed as the area percentage of the main peak relative to all detected peaks.
Why is LC-MS confirmation important?
Liquid Chromatography–Mass Spectrometry (LC-MS) provides definitive identity confirmation by measuring the exact molecular mass of the compound. This rules out isobaric impurities and confirms that the compound detected by HPLC-UV is the correct target molecule — not a structurally similar analogue.
What is the USP <85> endotoxin standard?
The United States Pharmacopeia Chapter <85> Bacterial Endotoxin Test (BET) defines limits for endotoxin contamination in injectable and research-grade materials. Passing this test confirms that endotoxin levels fall below the threshold that would compromise experimental validity in cell-based or in vivo research models.
How often are batches re-tested?
Every new production batch is independently tested before release. We do not rely on retest data from prior batches — each lot receives its own Certificate of Analysis. Historical test results are published above for full transparency.
