HPLC-UV purity analysis
Chromatographic separation measures the relative signal attributed to the main component and other detected peaks. A chromatogram supports interpretation of the reported purity.
Panel coverage: Essential and all higher panels.
LC-MS/MS identity confirmation
Mass spectrometry evaluates evidence for the expected compound identity. It complements chromatographic purity analysis.
Panel coverage: Standard, Professional, and Comprehensive.
Elemental impurities
Elemental analysis screens for the elements included in the selected testing scope. Confirm the specific elements and reporting limits needed for your sample.
Panel coverage: Standard and higher panels; expanded scope in Comprehensive.
Residual solvents
Gas chromatography evaluates selected residual solvents. Confirm the requested solvent panel and method suitability for your sample.
Panel coverage: Professional and Comprehensive.
Endotoxin and microbial limits
These are separate tests: endotoxin testing addresses bacterial endotoxin, while microbial limits assess specified microbiological attributes. Neither replaces a sterility test.
Panel coverage: Professional and Comprehensive.
Additional characterization
The Comprehensive panel adds sterility, particulate matter, and water content testing. Confirm sample quantity, test conditions, and reporting time before shipment.
Panel coverage: Comprehensive.
Interpret results within the tested scope
A method name or a passing result does not establish regulatory approval or suitability for human use. Request the documentation and reporting limits needed for your research before choosing a panel.
