Orthogonal analytical techniques selected to answer specific questions about identity, purity, endotoxin burden, sterility and residual water.
No single technique describes every characteristic of a sample. SinoChrom reports identify the method used and present the corresponding result against the submitted sample reference.
Chromatographic separation is used to assess the relative purity profile of a submitted sample and distinguish the principal detected component from other chromatographic signals.
Liquid chromatography coupled with mass spectrometry provides molecular-mass information used to assess whether the detected compound is consistent with the declared sample identity.
Endotoxin testing is performed using a Limulus Amebocyte Lysate assay in accordance with USP <85> under validated laboratory conditions.
Microbiological testing is used to assess the presence or absence of viable contaminating microorganisms in the submitted sample under the laboratory procedure applied.
Residual water measurement provides a quantitative moisture result when water content is relevant to characterization of the submitted material.
Identity and purity answer different analytical questions. Additional tests can be added when the requested characterization requires them.
Explore testing services →Each issued Certificate of Analysis is tied to a unique SinoChrom reference. Published reports marked Verified can be authenticated through the public verification page.
The submitted sample is linked to its report reference.
The analytical technique is identified alongside the reported result.
The report reference and QR code provide a direct authenticity check.
