Receiving record DEMO-RCV-26-007 · 17 September 2026

All companies, records, identifiers, methods and values in this packet are fictional. The example models document review for a teaching lab.

The lab received three vials in one shipment. The receiving technician copied the visible fields below. The stock IDs were assigned on arrival. No photograph or packing list with vial-to-lot mapping is attached.

D2 and D3 came in the supplier’s shipment email. D4 arrived in a separate internal forwarding message. No submission form, sample-label photo or sample-to-lot cross-reference accompanies D4.

Decision rule for this exercise

Record a vial as documented for the exercise when its material and lot match a CoA and all three reported results meet their stated criteria. Record a hold for a result when a matched CoA has a result outside its criterion. Record a hold for traceability when the vial-to-lot link is missing. Document any outstanding follow-up separately.

These are classroom record statuses. They describe the available evidence for the exercise.

Test results

Attribute and methodStated criterionReported result
Intact-mass agreement · LC-MS, deconvoluted neutral average mass1124.10–1125.10 Da1124.71 Da
Main peak · RP-HPLC-UV, relative integrated area≥ 98.0 area %98.6 area %
Peptide content · calibrated LC-UV assay against a reference standard4.50–5.50 mg/vial4.92 mg/vial

Main peak area uses the main integrated peak area divided by the total integrated area under this LC-UV method. The content result uses a separate calibrated assay and is reported in mg/vial.

The results apply to the described test sample. The CoA records the issuer’s lot-level statement. It gives no receiving stock ID.
