    P71 : Seaweed Carbohydrates

Our expertise with ion chromatography has allowed us to develop a protocol for determining the cabrohydrate composition of brown seaweeds.

This analysis package will give contents for the neutral sugars glucose, xylose, mannose, arabinose, and galactose, as well as the deoxy sugars fucose and rhamnose, the sugar alcohol mannitol, and the uronic acids mannuronic acid, guluronic acid, glucuronic acid, and galacturonic acid.

This analysis package is tailored towards the analysis of brown seaweed. If you would like us to analyse the carbohydrate composition of red or green seaweed please get in touch.

Constituents Determined

For every constituent determined via wet-chemical analysis each sample is analysed in duplicate and we provide the compositional data for each replicate along with the average value and the standard deviation between the duplicates. Our analytical protocols typically provide results with a high level of precision, as detailed here.

Examples of the data reports generated can be viewed on the Celignis Database. Please log on to the guest account using email "test@celignis.com" and password "celignis".

Equipment Used for Seaweed Carbohydrates Analysis

Ion Chromatography

A Dionex ICS-3000 system that is equipmed with electrochemical, conductivity, and ultraviolet-visible detectors.


An autoclave is used in the protocols for the determination of the lignin and structural sugars (cellulosic and hemicellulosic) contents of samples.
