Procedure to resolve duplicate IGSN registrations

Accidental multiple IGSN registrations for the same sample

Example

A user brings a sample to a lab for analysis without knowing that the sample is already identified by an IGSN. The lab assigns a new IGSN, based on the assumption that no prior registration exists.

Procedure

Already existing IGSN registrations must be respected to maintain an unambiguous identification of a sample. The second registration

Subsample taken outside of the home institution

Example

Cores and/or subsamples are shipped to other institutions for additional scans, detailed analyses, and subsampling/splitting.

Procedure
