    From Jerry
    "Distilled water (50°C) .............. 750   ml
    Sodium sulfite (anhy) ............... 100   g
    Sodium bisulfite .................... 25.0 g
    EDTA, Na4 ........................... 2.0 g
    Sodium citrate ...................... 5.0 g
    Distilled water to make ............. 1.0 l

    And from your post from ‘07:
This looks correct, it is for the stock solution which is diluted 1 part stock to 4 parts water for use.
