Sodium Adsorbtion Ratio (SAR) Reagent Wanted

[CHris__H]

Hi all, I am after a Sodium Absorption Ratio (SAR) Reagent EDTA Solution for a titration method to conduct SAR tests. I believe the main solutions to conduct this test is a Calmagite Indicator Solution and the above reagent solution. Hanna instruments don't stock the reagent solution anymore

I would love any help in obtaining some solution from knowledgeable members.

my thanks in advance.

EDTA solutions are common for determine Calcium, Magnesium and others.
Calmagite is not so much known, but a substitute called Eriochrom Black is in use.

Thanks for your reply ChemBeier really appreciate you taking the time to reply. Do you (or anyone else) know if there is an "off the shelf" titration kit for testing SAR using a titration method (apart from the Hanna instruments discontinued kit)? I am not a chemist or trained in chemistry but could conduct simple titration-style testing and calculations to achieve SAR values.

kindest regards
