University mass-spec core qualified 12 Lyochem reference standards for a 5-year departmental SOP

Challenge

The core facility's Director was responsible for maintaining the departmental peptide-reference-standard inventory used by multiple PI groups for analytical-method validation and bioassay reagent qualification. The previous supplier had relabelled SKUs twice over a four-year period and changed the analytical-method provenance description on the lot report each time, which made the SOP referencing the standard's identity unreliable across multi-year audit windows. The Director needed a supplier with stable catalogue identity, consistent analytical-method language on the lot report, and a stability programme long enough to cover the typical multi-year SOP refresh cycle.

Approach

Lyochem's atelier team ran a one-time qualification campaign across the 12 SKUs the core facility identified as critical for cross-PI use, providing per-lot data packets aligned to the same USP / EP / ICH method-provenance references on every release. The 12-month −20 °C stability programme on every released lot covers the typical departmental SOP refresh window, and the catalogue SKU identity is locked at the slug level so re-orders against the same SKU draw from the same documented synthesis route. The Director and the core facility's analytical-chemistry liaison were given direct atelier contacts for lot-to-lot continuity questions outside the standard inquiry channel.

Outcome

All 12 SKUs cleared the core facility's qualification within 4 weeks of first shipment. The departmental SOP was updated to reference Lyochem catalogue slugs and the harmonised method-provenance language; the SOP has now run for two refresh cycles without identity-drift complaints from the multiple PI groups using the standards. Re-orders against the same SKUs continue to draw from the same documented synthesis route with the same per-lot data packet template.
