Abstract
The component of Titan yellow most reactive towards magnesium has been isolated from the acetone-extracted dye by adsorption chromatography on Sephadex G–10. It is so reactive that it can be used at a concentration as small as 0·008 per cent., at which concentration the response is linear between 20 and 150 µg of magnesium. Values found for the magnesium content of silicate minerals agree with those obtained by spectrographic and gravimetric methods.
