Standardizing ID-Labels for seaweed samples used for chemical composition analyses and refinery processes in Nordic and European research projects

Introduction

Seaweed samples can be divided into two groups:

1. Small samples (½-3 kg wet weight (ww)) often used for chemical content analyses including seasonal variation and testing different cultivation conditions or preliminary lab scale experiments on storage, extraction, separation, fermentation, etc.
2. Larger samples (>3 kg ww) for lab- or pilot scale experiments on storage, extraction, separation, fermentation, etc.

Seaweed samples will always have the following information-tracks:

1. Sample Code: A ID containing the most important information and the sample code will follow the sampled biomass from harvest to final research results.
2. Seaweed Processing Code: The sample code will be extended with 8 digits and 1 letter if processing of biomass occurs.
3. Batch Number: A code describing details about the harvest and origin of the seaweed.
4. Sample Overview:  An Excel file describing all details about the sample: first sample code, then species, grinding, freezing/drying specifications, seeding and harvesting information, planed aim of the sample (e.g. polysaccharides), place stored, seaweed processing details, analyse results, etc. Maintained by the sample provider.
