Importance of Instrument Validation for Accredited Food Export Testing Labs 1 Overview • • • • • • Why laboratory accreditation for food testing Overall requirements for accredited food testing laboratories Quality checks in the laboratory related to analytical instrument qualification Qualification vs. Verification Essential steps and example templates for Instrument Qualification: DQ, IQ, OQ, PQ Requalification: when, what Reference material: www.labcompliance.com/agilent Available until March 10, 2014 Copyright Slide 2 Value of ISO 17025 Product shipped from country A to B Country A Country B • Routine testing only tested in one accredited laboratory of country A • International comparability of test results through traceability to the same standard • Confidence in test results through estimated and documented measurement uncertainty Copyright Slide 3 Overall Requirements of ISO 17025 Sampling Sampling plan & sampling documentation Sample handling Sample identification & protection of sample integrity Testing Monitoring the quality of test results Test reports Test conditions & test results, with estimated uncertainty Record maintenance Ensure record integrity & security Controls across all workflow steps • Validation of analytical • Qualification of material • methods & procedures • Traceability • • Equipment calibration • Handling Out-of-specification validation & maintenance results • Qualification of personnel Controlled environmental conditions Written procedures Quality system controls across the laboratory Documentation control, corrective & preventive actions, complaint handling, supplier & subcontractor management, internal audits, change management, management reviews, continuous improvement, product reviews Copyright Slide 4 Quality Checks in Laboratories • Quality control checks – Verifies accuracy of sample analysis • System suitability tests – Verifies that the system performs according to analysts expectations • Analytical methods validation – Proof that analytical procedure does what it purports to do • Analytical instrument qualification – Forms the base for generating quality data – Proof suitability of the instrument for intended use Copyright Slide 5 Equipment Calibration, Qualification, Maintenance – ISO 17025 • Laboratory equipment should be furnished with correct performance of tests • Equipment and software shall comply with specifications relevant to the tests • Before placed into service, equipment should be calibrated or checked to verify specifications • Shall be operated by authorized personnel • Should be uniquely identified • Procedures for safe handling and preventive maintenance • Defective equipment shall be taken out of service • Shall be labeled to indicate status of calibration Copyright Slide 6 Verification vs. Qualification Verification (ISO/IEC Guide 2) Confirmation by examination and provision of evidence, that specific requirements have been met Operational Qualification (Pharma, PDA) Documented verification, that a system operates according to written and pre-approved specifications throughout all specified operating ranges Assumption: Specific requirements are defined Assumption Requirements are defined for specified operating ranges Verification Step: Examine and confirm that specific requirements are met Qualification step Examine and confirm that preapproved requirements are met Copyright Slide 7 United Nations – Complying with ISO 17025 Guidebook Equipment • All new equipment must be checked for correct functioning before being placed in routine service. • This should include checks against the manufacturer's specifications and checks to confirm that the equipment gives satisfactory results when used to make the measurements for which it is intended. DQ – IQ- OQ -PQ Copyright Slide 8 Qualification/Validation Phases 4Q Model Design Qualification Installation Qualification Operational Qualification Performance Qualification User requirement specifications Functional specifications Operational specifications Vendor qualification Check arrival as purchased Check proper installation of hardware and software Test of operational functions Performance testing Test of security functions Test for specified application Preventive maintenance On-going performance tests • Based on official standard (USP <1058)> • Well known to industry and agencies • Most safe approach for food testing labs Copyright Slide 9 Qualification Project Plan Template Scope of the Plan Product Description Validation Strategy Responsibilities Supplier Assessment Risk assessment Testing Strategies DQ IQ OQ PQ Traceability matrix Procedures Approval Documentation control Copyright Slide 10 Design Qualification (DQ) Activities and Documentation • Vendors – Design, develop and manufacture instruments in quality control environment, e.g., ISO 9001:2008 – Develop functional and operational product specifications • Users – Develop user requirement specifications – Verify that the vendor’s instrument meets user’s requirements: product specifications, delivery and support – Verify that the vendor operates in a quality system environment Copyright Slide 11 Design Qualification - Template Function/ Performance User Requirement Supplier Specification Comment yes/no Function 1 Function 2 Physical Requirements Construction Requirement Vendor Requirement Copyright Slide 12 Installation Qualification (IQ) Vendor • Provides the user with environmental specifications and a site prep document • Provides • Offers services for IQ with inspection ready documentation User • Verify that facilities, utilities, and environment meet vendor requirements • Assemble and install equipment • Perform initial diagnostics and testing • For complex equipment: run reference sample • Document installation, including drawings Copyright Slide 13 Equipment Documentation for IQ Identification Manufacturer Best HPLC Model D4424A Firmware revision 1.00 Serial Number E4431A Internal ID (Asset number) D33243 Current location Glab4 Size (w x b x h) (cm) 30x22x7 Condition when installed New Supplier contact phone for 1+541-64532 services Example: HPLC detector Copyright Slide 14 Operational Qualification (OQ) Vendor • Provides services for OQ with traceable tools • Delivers inspection ready OQ documentation • Makes recommendations for frequency of requalification User • Test functions to verify that the instrument operates in the user’s environment as intended by the manufacturer and required by the user. • Test secure data handling, storage, back-up and archiving • Tests can be holistic or modular. • Tests can be done by users or qualified designees.
