Hi Kirk,
I am glad to hear from you! There are at least 6 different "kinds" of chlorophyll, A through F. Different solvents may extract different types, or worse, alter different types. Someone suggested that Heptane would extract Chlorophyll B from a more hodge podged mixture. Yes, "hodge podged" is a recognized Scientific term.
We are still waiting for you to make a T-grain emulsion.
