Quality Control procedure

The Quality Control (QC) procedure at the Spinoza centre is composed of a weekly and monthly protocol consisting various tests and checks. The QC is usually performed by the scan-assistants of the Spinoza centre, supervised by Tinka and Steven. All relevant data is saved into an excel-file. Below, both procedures are summarized.
