Hi, for determination of K percentage in a fertilizer, I make calibration curve mixing standards and unknown. As 10 ml of unknown to all balloons and different amounts of standard, 1 balloon only has unknown without any standard. Why is that? Shouldn't the b from y=ax+b and signal of the balloon without standard be the same? If they are not what should I do? I'm confused, please help

8:50 the one thing you missed out on mentioning is the inverse square law. If you plot the potential energies of the ions between two poles, you get either a knife-edge (i.e. 1/x^2) where small ions roll off, big ones don't have time. Or you get a parabola-shaped ditch (x^2) where the big ions have enough momentum to get all the way up the walls. Don't know if it'll help anyone else, but I always like watching balls roll down planes.

can anyone tell me why there's error between website calculation and hand calculation? When both methods calculated, there is no charge. So this "error" is just used for mentioning that small difference can be detected by MS?

Wow, it's amazing! "carbon 12 by definition has a mass of exactly 12, and therefore, if you look at carbon 13, it is not the mass of carbon 12 plus one neutron. It's a little bit less than that." You explain this extremely clear!!!
