Standardizing Id-Labels For Seaweed Samples Used For Chemical Composition Analyses And Refinery Processes In Nordic And European Research Projects

<strong>Introduction</strong> Seaweed samples can be divided into two groups: 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. Larger samples (&gt;3 kg ww) for lab- or pilot scale experiments on storage, extraction, separation, fermentation, etc. Seaweed samples will always have the following information-tracks: <strong>Sample Code: </strong>A ID containing the most important information and the sample code will follow the sampled biomass from harvest to final research results. <strong>Seaweed Processing Code:</strong> The sample code will be extended with 8 digits and 1 letter if processing of biomass occurs. <strong>Batch Number:</strong> A code describing details about the harvest and origin of the seaweed. <strong>Sample Overview:</strong> An Excel file describing all details about the sample: first <strong>sample code</strong>, 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.
