Please consult google for an answer and not an answerer.

Note : 1 ppm = mg/l and DMSO (must be pure) has a density D (20/4) 1.100.

On other part , what a kind of indigo are you using ?

Here a data sheet (from google) :

You can increase the amount of solvent and solute to reduce the error.

For example, you may add 10*100 mg(1g) indigo to 1*100 ml DMSO to get the solution.
