Frequently asked questions
Pharma is committed to helping you access trusted lab and pharmacy solutions, with expert help at every step of the way.
What is the relationship between reference standards and working standards in the LIMS?
Working standards are prepared from reference standards through a qualification process. The LIMS maintains bi-directional traceability — every working standard lot is linked to its parent reference standard, preserving the analytical traceability chain.
How are working standard lots qualified before use?
Qualification involves standardization against the parent reference standard. Results are recorded in the system with approval workflow — a working standard is only released for analytical use after passing qualification.
How are working standards issued to analysts for testing?
Issuance is managed digitally with quantity, date, analyst, and intended test batch recorded. The system ensures only qualified, in-date working standards are available for issuance.
How are working standard expiry and use-before dates enforced?
Automated expiry and use-before alerts notify analysts and supervisors before dates are reached. Expired working standards are automatically blocked from issuance.
Can both internally prepared and externally procured working standards be managed?
Yes. The module supports internal lot creation (in-house preparation) and external lot registration (commercially procured working standards), both managed within the same framework.
How does the system track working standard stock and consumption?
Real-time stock balance is maintained per working standard lot, with automatic updates on each issuance and vial preparation event — providing accurate consumption data for planning.
What documentation is generated during working standard vial preparation?
Vial preparation records capture analyst, date, quantities, concentrations, and labels — generating a complete preparation record linked to the working standard lot.
How does the module ensure working standard traceability to pharmacopoeial standards?
The traceability chain from pharmacopoeial reference standard through secondary reference to working standard is maintained within the system — meeting GLP requirements for metrological traceability.
What reports are available for working standard management?
Reports include WS vial preparation, usage report, destruction records, stock card, and COA — providing complete documentation for audit and regulatory review.
How does working standard management support data integrity compliance?
Complete audit trails, electronic signatures, and version-controlled records for all working standard activities ensure that analytical results are traceable to authenticated, validated standards — a fundamental data integrity requirement.
