Mass Spectrometry MS 

nice one

Hold up! Why did you have to learn about this stuff?

I'm a a 16 yo at college, i'm just learning about this, wut?

Arman Ashourlou . Check out Avogadro and the mole. Basically carbon is assigned a mass of 12 and every this calculated from that.

Cat. Parametrization

Parametrization Can convert ELECTRIC To MAGNETIC fields And Vice versa

Armani : Before mass spectrometers there were 3 ways to find the atomic masses : -- The stoichiometric law : weight 10g of pure magnesium, burn it in free air, weight the obtained MgO, it will be 16.6, and the number of moles is constant = 10/mass(Mg) = 16.6 / (mass(Mg)+mass(O)) -- The law of perfect gases : each molecule is a small ball, the temperature is the kinetic energy per ball, and by Newton's law at constant temperature and pressure then the number of molecules per volume doesn't depend on the mass of the balls, see en.wikipedia.org/wiki/Kinetic_theory_of_gases#Equilibrium_properties -- Law of Dulong-Petit : in a crystalised solid the temperature is that each atom is vibrating around its mean position, the kinetic energy is then mv^2 and at thermal equilibrium it is constant from one atom to the other, this is the temperature T = 2mv^2/3, thus the energy needed to increase the temperature of one Kelvin depends on the number of atoms not on their masses.

electric field is deflecting all ions through the same angle however magnetic field deflects them according to their mass/charge ratio. As we know that centripetal force created is because of the magnetic field applied in the plane prependicular to the direction of ions. (mv2/r = ZevB)

Thanks Mobahil. Unfortunately, I still don't understand the point of having a magnetic field. Why does the mass/chargo ratio matter?

well how can you differentiate two molecules with different masses without magentic field? do u have any other possible ideas ?

Ahhh I gotcha. Okay ! Thank youuu. Just had my epiphany moment. Haha.

Parker Leigh you are welcome :)

Henry Truong .. more like: OhhhhhOMGMSMSMSMSM :-}

Naeemullah Khan it used to be. But after invention of centrifuge everyone uses that now.

bad

it's not even cost efficient.

So why dont you invent something else

+Alex Vincent bad and not even cost efficient.
