Dear Communities:

1)I've learnt that conductivity meter can be used to measure the so called "conductivity ash", such as proposed by Mettler Toledo device (https://www.mt.com/my/en/home/products/Laboratory_Analytics_Browse/pH/benchtop_meter/SevenExcellence/S470.html)

However, in documentation, the proposed application is only for "ash in sugar".

2) I would like to use that method to measure the ash in a liquid extract obtained from seaweed (thus having quite a big amount of ash content as measure in the "classic" way (burning it in a furnace))

3) My question is: will it make sense to use conductivity ash as an approximation of ash content by "calibrating" the conductivity on a dozens of samples where both methodology will be used.

4)The advantages would be the following

-non destructive to the whole sample

-quicker

-can work with smaller amount of sample or diluted sample

5)the goal will be to implement it to only one specie of seaweed coming from similar environment thus limiting intraspecies variations or geographical issues.

Thanks !

Arthur
