Detection of the Complete Mass Spectrum Full Scan

1 Detection of the Complete Mass Spectrum (Full Scan) 

Scan range (Da) Dwell time per mass Ion trap (s/Da) Quadrupole (s/Da) Sensitivity ratio ion trap/Quadrupole 

The longer dwell time per mass leads to the highest sensitivity in the recording of complete mass spectra with ion trap instruments. Compared with beam instruments an increase in the duty cycle is achieved, depending on the mass range, of up to a factor of 100 and higher. 

Dwell Times t per Ion in Full Scan Acquisition with Ion Trap and Quadrupole MS Mass range 50 - 550 Da (500 masses wide), scan rate 500 ms  

Ion storage during ionization. Ionization time can vary, typically up to t = 25 ms at simultaneous storage of all ions formed t- = lms/Da
