2018 Mass Spectrometry & Purification Techniques  
In Mass spectrometry separation of ions takes place on the basis of there mass to charge ratio. Mass spectroscopy is an advanced and powerful technique for qualitative and quantitative analysis. Detector plays an important role in mass spectrometer for the separated charged ions. Results are displayed as spectra of the relative abundance of detected ions as a function of the mass-to-charge ratio. The detector with desirable properties in mass spectrometer should have high amplification, Fast

Type of mass detectors and there working capacity reviewed in the present article. These mass detectors are a] Electron Multiplierand Flexar SQ 300 MS Detector. It is also observed that evoluation in mass spectrometry always takes place as per the type and need of analysis.
