Got my TFkit today. Last I remember being this excited was in my chemistry labs. Every test is straightforward but I got questions:
1) FAS/DPD. When I start counting R-0871 drops, is the endpoint when the mixture is as clear as the original water sample? Or will there still be a very slight residual pink hue? I was throroughly swirling after each drop. I added 2-3 extra drops but the light pink hue never went away.
2) With the DPD powder, what exactly is a "heaping scoop?" Is it a level scoop? Or a scoop with a little extra mound on top?
3) TA. When counting R-0009 drops, is the endpoint when a drop finally produces an instant red cloud? Because the red cloud disappears after a little swirling around. Or is the endpoint when the entire mixture is red, even after swirling several times?
