    Swirling and titration tests

    Will the results of my titration tests, e.g., FAS-DPD, be effected if I add several drops of reagent before swirling? Sometimes when I expect a high number I'd like to add 4-5 drops and then swirl knowing there is room to spare.

    Thank you,
    Ed

    If you have a real good idea of where the current Fc level is then u don't really have to swirl it after every drop.I would swirl it every 2-3 drops or you could get off by 1 ppm which isnt a big deal but if you got a nice test kit why not.check into a Taylor speedstir with stir bar it is a cool gadget to have for testing.
