Chemical name: Palmitoyl Proline

The specimen was shipped at room temperature on behalf of Mr Olivier DENNY from DEFITRACES.
It was treated according to the ANADAG procedure PG 0204 for receipt, identification and storage.
The characteristics of the transport, of the receipt and of the storage in ANADAG facilities were all registered and are summarised in the following table.
Temperature during the transportation: RT = room temperature
Transportation date: 19.03.10
Date of receipt at the test facility: 22.03.10
Amount received: 50g
Condition of specimen upon receipt: Ok
Storage temperature: RT

The maximum temperature was daily recorded and was below 30 °C during the storage period
The test item was stored away from moisture and direct light.
The sample was submitted to the test as received.
