Undergrad Mass Spectrum Analysis: Identifying Mass & Charge
schoolwork would be nice, seminar for graduated ;) mass $$m$$ charge $$z$$ peak in spectrum $$p_i$$ original mass of ion $$M$$ What I essentially wanted to ask: Do you need a reference mass (e.g. a bucky ball or a carbon atom) with a known mass for measuring a spectrum of a new molecule or can...- mikeb94

Undergrad Mass Spectrum Analysis: Identifying Mass & Charge
sorry, didn't know how to use Latex here ;) $$ p=\frac{m}{z}$$ $$ p_1=\frac{M_r+z_1}{z_1}$$ $$ p_2=\frac{M_r+(z_1-1)}{(z_1-1)} $$ $$ z_1 =\frac{p_2-1}{p_2-p_1} $$ $$ M_r = \frac{1}{\frac{1}{p_1-1}-\frac{1}{p_2-1}}$$- mikeb94

Undergrad Mass Spectrum Analysis: Identifying Mass & Charge
Hello everyone, I'd like to know how to identify the charge and the mass in a mass spectrum. How do I get the mass corresponding to a peak. I know how they are related p=\frac{m}{z} p_1=\frac{M_r+z_1}{z_1} p_2=\frac{M_r+(z_1-1)}{(z_1-1)} z_1 =\frac{p_2-1}{p_2-p_1} M_r =...- mikeb94
