What is the mechanism for ESI positive and negative ion mode?

20 February 2017 1 1K Report

Hi all,

Many commercially available MS has "positive" and "negative" ion mode even the ones that use ESI. What is the mechanism for these? (by mechanism I mean electron impact ionization or or chemic ionization..)

Thanks,

Cece

some one asked this question before. See the link https://www.researchgate.net/post/What_is_the_difference_between_positive_ionization_mode_negative_ionization_mode_and_multiple_reaction_monitoring_MRM_mode

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)...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
