    Can anyone tell me the right answer to this problem....

    What techniques can be used to separate non-volatile substances?

    Thin-layer Chromatography
    Gas-liquid Chromatography
    Sublimination
    Distillation
    Steam Distillation

    Also, is there an error in the biology section? This question ask what is the major intracellular buffer and the answer choices are: TRIS, Acetate, Phosphate, Bicarbonate, and Calcium Carbonate. I choose Phosphate and got it wrong. There is a similar question in the 2011 DAT Destroyer (#312) and the correct answer is phosphate and that's why I marked that answer in the 2009 ADA test but it marked it as wrong. I don't get it.
