Question

What is the function of quadrupole mass spectrometer?

Answer 1

The quadrupole consists of four parallel metal rods. Each opposing rod pair is connected together electrically, and a radio frequency (RF) voltage with a DC offset voltage is applied between one pair of rods and the other. Ions travel down the quadrupole between the rods.

Answer 2

The quadrupole comprises of four parallel metal bars. Each restricting pole combine is associated together electrically, and a radio recurrence voltage with a DC balance voltage is connected between one sets of bars and the other. Particles travel down the quadrupole between the poles. Just particles of a specific mass-to-charge proportion will achieve the locator for a given proportion of voltages: different particles have unsteady directions and will slam into the poles. This grants determination of a particle with a specific m/z or enables the administrator to check for a scope of m/z-values by constantly shifting the connected voltage.Mathematically this can be demonstrated with the assistance of the Mathieu differential condition.
