What does the resolution of quadrupole mass analyzer depend on?

Hi, I was curious to know what factors affect the resolution of a quadrupole mass analyzer. I find a lot of electrical settings that may affect the mass of the ions that are being transmitted. Is...

Can mass spectrometry tell something is radical ion?

is it possible that mass spectrometry can tell radical ions or is it not not possible? (Because loss of an electron will result in only 0.0005 Da, there is no instrument with such high...

What is a relationship between ion transmission and grid in Time-of-Flight Mass Analyzer?

Hi all, My understanding about the grid used in ToF is it is useful to reduce the broadening due to the varied kinetic energy of the ion. But also it may reduce transmission (90% or less). Is...

Why do we lose transmission when increasing the drift length of TOF?

Resolving power of TOF increases with longer drift time (mass/delt(mass) = (t/delt(t) using the kinetic energy ((1/2)*mv^2) and potential energy(z*e*V) ). t is the centroid of drift time. delt(t)...

How do people study oxidation state of metal ions?

How do people study the oxidation state of divalent metal ions? The difference is number of electrons, which are very small in mass. How do people actually study this experimentally?
