3
Q
M/z = radius = 1/ deflection
A
Agr kisi ka mass zada hai mtlb uska radius zada hoga mtlb use deflection Kamm hoga
4
Q
Koine se peak ki intensity zada aati hai
A
Base ion peak ki
Jis mass pr sbse zada ions milte hahi use he hum highest intensity kak Maan late hai
5
Q
Metastable ion kaise banta hai
A
Kisi ek molecule ka 2 baar fragment ho jaaye
6
Q
35 Cl, 37Cl = molecular mass
Cl = 35.5 = atomic mass
A
7
Q
Relative abundance
35 Cl = 100 %
37 Cl = 33%
A
35 cl =76%, 76÷76 = 100 %
37 Cl = 24% , 24÷76 = 33%
