An important enhancement to the mass resolving and mass determining capabilities of mass spectrometry is using it in tandem with chromatographic and other separation techniques. A common combination is gas chromatography-mass spectrometry (GC/MS or GC-MS). In this technique, a gas chromatograph is used to separate different co…
WebThe duty cycle for recording each mass in the spectrum is generally poor, and the higher the resolution or the wider the mass range the poorer the duty cycle. An array detector allows simultaneous acquisition over a range of masses thereby improving the duty cycle when used to record a spectrum. the psycholinguistics of metaphorWebAug 17, 2007 · In such circumstances analytical identification may require only a limited number of masses (or mass regions) to be continuously monitored.
