M/z = radius = 1/ deflection
Agr kisi ka mass zada hai mtlb uska radius zada hoga mtlb use deflection Kamm hoga
Koine se peak ki intensity zada aati hai
Base ion peak ki
Jis mass pr sbse zada ions milte hahi use he hum highest intensity kak Maan late hai
Metastable ion kaise banta hai
Kisi ek molecule ka 2 baar fragment ho jaaye
35 Cl, 37Cl = molecular mass
Cl = 35.5 = atomic mass
Relative abundance
35 Cl = 100 %
37 Cl = 33%
35 cl =76%, 76÷76 = 100 %
37 Cl = 24% , 24÷76 = 33%
Natural abundance
35 cl 76%
37cl 33%
