What is a certificate (of analysis)?4

Definition ISO Guide 31:2000 defines certificates as:“Document containing all the information which isessential to the use of a certified referencematerial” Please also note:“Without the certificate, the material (the CRM),however costly its production, is valueless.”“The certificate should not be parted from the CRM.”5

Definition ISO Guide 31:2000– Defines content and structure of certificatesCurrently under revision!6

Content of a certificate Possible content acc. to ISO Guide ��–Name and address of certifying organisationTitle of the documentName of the documentCode and batch numberDescription – relevant informationIntended useInstructions for useHazardous situationLLevell off hhomogeneityitCertified property values and uncertaintyTraceabilityDate of certificationPeriod of validityStability, transportation and storage instructionsShelf life/expiry date .CAN be included with a CRM!Not a MUST!7

CertificatesCet cates – USUSP CCRMCertified Property Value: 1.000 0.001 mg/mg10

CertificatesCet cates – USUSP CCRM Caution with uncertainty:– Very small, looks good on a first glance– However,However in this case: Uncertainty does not take into accountwater content, needs to be determined by user through KarlFischer-titration– Was raising discussions in the pharmaceutical community Smaller than comparable materials from metrology institutes(see NIST CofA) Traceability “hidden”, as with the NIST CofA as well– Both materials only traceable to NIST resp. USPin house methods– Info on traceabilitiy can be more detailed with CRMs from othersources (e.g. some ERM materials)11

USP – Will tthereUSe e be furtherut e CCRMs?s Pertaining discussion on CRMs inside USP:„„TheUSP Reference Standard projectp jteam seems to have mixedfeeling whether or not the CRM would add value to current practicesfrom Industry perspective.“(Comment at: unity aapspharmaceutica com; Feb 2009) No further CRMs for the USP-NF since more thanthree years12

Primary pharmaceuticalreference standards Previous webinar: Recommended approach forprimary RS (see also EP General text 5.12.)– UsuallyUll purityit off 95%95%– Full characterization and documentation of Identityy (with(several qqualitative techniques:qNMR, MS, IR, UV/VIS,Elemental analysis, where appropriate X-ray structure analysis) Purity (with HPLC impurity profile)Identify peaks with area percentage 0.1%M b checkMaybeh k relativel ti response factorf t off impurityiit behindb hi d peakk. continued14

Primary pharmaceuticalreference standards Recommended approach for primary RS(continued)– Full characterization and documentation of Residual solvents by GC-Headspace methodsWater content by Karl-Fischer titrationLoss on drying (sum of water and residual solvents)Melting point (rough purity/identity information)Sulphated Ash (inorganic impurities) Assay, for primary RSs from purity calculation (with the results from allrelevant examinations) plus at least one additional independent method(e.g. titration)15

Secondary pharmaceuticalreference standards FDA guidance from previous webinar– . A working standard (i.e. in-house(!) or secondarystandard) is a standard that is qualified against and usedinstead of the reference standard .– Desired qualificationsf No requirement of full proof of structureProof of identity (e.g. by IR or MS) against primary RS sufficient Determination of assay of secondary RS against original primary RS26

ClosingCos g remarkse a s PDF of presentation downloadable from our websitehttp://pharma.lgcstandards.com/g– When on website, look under ‘Events’– PDF is approx. 5 MB This webinar last one of our Spring series of webinars– We will repeat it in Autumn 2013 for Europe and Asia The last webinars had more than 100 registrants, so we are quite happyabout the success– We will also present the highlights soon for our Americancustomers43
