Testing MMS and Citric Acid for potency

Is there any way to test mms and citric acid solution for potency and strength. I notice that when I mix the mms and citric acid , 50%, the color of the mixture before adding water is a very very light yellow, however, when watching some to the videos it seamed to me that the color was a slight brown color. Can one test the mms, citric acid or mixtures made after adding water? To further explain the question: Can you test the mms before activating; can you test the citric acid by adding some water to it; and finally can you test the activated mms with say 4 or 8 ounces of water?
