Question 7 of 15 Map Occurs First Occurs Last lons are accelerated out of the ion source and into the analyzer tube, all with the same kinetic energy by a voltlage applied between the ion acceleration plates. The magnetic field deflects the ions on a circular with a radius that is dependent on the m/z of the towards the detector at the end of the analyzer tube Scroll down to see all six statements. is created by varying the magnetic field A mass spectrum strength, therefore altering which ions reach the detector The ions encounter a magnetic field applied perpendicular to their direction of travel lons deflected on a circular path with a radius equal to the radius of curvature will travel through the slit leading to the deleclor. Heavier ions are not deflecled enough and lighter ons are deflected too much to reach the detector Gaseous molecules enter the ion source where they are ionized through collisions with electrons.

Explanation / Answer

the step is ionization

1) ionisation

in this step the molecules are ionized

this is done by removing their outer electrons

2) Accelerator

in this step

the ions are accelerated of the ion source

this is done by applying a voltage

3) deflection

in this step

ions are deflected by the magnetic field

and

The amount of deflection depends on the mass and charge of the ions

4) detection

the ions are detected in this step

so

the steps are as follows

a)   gaseous molecules enter the ion source where they are ionized through collisions

b) ions are accelerated out of the ion source and into the analyzer tube , all with the same kinetic energy

c) the ions encounter a magnetic field applied perpendicular to their direction of travel

d) the magnetic filed deflects the ions on a circular path with a radius that is dependent on the m/z of the ions

e) ions deflected on a circular path with a radius equal to the radius of curvature will travel through the slit to the detector

f) a mass spectrum is created by varying the magenetic field strenght
