Mass Spectrometer










*Okay. I promise to edit this post when I drew a clearer diagram ><*

A: Vapourisation Chamber
-to vapourise the solid or liquid sample into gas


B: Ionisation Chamber
-to ionise the sample gas (consists of atoms and molecules) by knocking or bombarding the gas sample with high energy electrons emitted from the heated tungsten filament so that unipositive ions are formed


C: Acceleration Chamber
-to pull and accelerate the positive ions into high but constant velocity so that a stream of ions passes through the small openings at the cathode plates


D: Magnetic Field
-to deflect the stream of ions into different beams of ions according to their mass to charge ratio


E: Detector
-to deflect the beam of ions of the same m/e ratio that strike the plate so that a signal is sent to the recorder through the amplifier


Amplifier
-to magnify the signal so that it can be easily and acurately recorded by the recorder


Recorder
-to record the different beams of ions of various m/e ratios with respect to their abundances so that a mass spectrum is produced

Chemistry is getting nicer 8D
