decribe what happens in the mass spec
a voupourised gasous atom is added to the mass spectron, an electron gun fires electrons at the sampple knocking off electrons cuasing it to become a negative ion , the ions are accelerated between to negative places
1 of 5
what happens after the places accelerate the electron
the negative plates deflect the electron according to its mass, it deflect lighter ions because they have a smaller mass, then the signal is amflified and the recordings sre dectected
2 of 5
isotopes of chlorine
Cl35 Cl37 peaks at 70 for (CL35-Cl35) peaks at 72 for (Cl35-Cl37) peaks at 74 for (Cl7-Cl37)
3 of 5
bromine isotopes
br79 br81
4 of 5
ratios for the isotopes of chlorine and fractions
9:6:1 (CL35-Cl35) 3/4 x3/4 for (Cl35-Cl37) 1/4x 3/4 + 1/4 x 3/4 for (Cl7-Cl37) it 1/4 x1/4
