Performance specifications 

Sensitivity* Positive electrospray (HESI) 

A 5 µL injection of a 200 fg/µL reserpine solution will produce a  minimum signal-to-noise ratio of 1,500,000:1 for the transition of  the protonated molecule at m/z 609.3 to the fragment ion at m/z 195.1 when operated in SRM mode with Q1 and Q3 resolution  set to 0.2 and 0.7 Da FWHM respectively. 

Atmospheric pressure chemical ionization (APCI) 

A 5 μL loop injection of a 200 fg/μL reserpine solution will  produce a minimum signal-to-noise ratio of 100,000:1 for the  transition of the protonated molecular ion at m/z 609.3 to the  fragment ion at m/z 195.1 when operated in SRM mode with  Q1 and Q3 resolution both set to 0.7 Da FWHM. Negative electrospray (nHESI) 

A 5 μL loop injection of a 200 fg/μL chloramphenicol solution will  produce a minimum signal-to-noise ratio of 1,500,000:1 for the  transition of the deprotonated molecular ion at m/z 321.0 to the  fragment ion at m/z 152.0 when operated in SRM mode with  Q1 and Q3 resolution set to 0.7 Da FWHM. 

Mass range

m/z 2–2010 

Resolution

Q1 and Q3 adjustable to 0.2 Da peak width (FWHM) across the  entire mass range 

Scan rate 

• 15,000 amu/second at a resolution of 2 Da FWHM 

• Up to 600 SRMs/sec (for resolutions from 0.2 through 2.0  FWHM) 

• Polarity Switching: 5 msec electronic switching time that  includes signal stabilization  

Mass stability 

Mass assignment will be within ± 0.1 Da over a 24-hour period.  The laboratory room temperature must be maintained between  18–27 °C (65–81 °F). The room temperature may not change by  more than 5 °C (9 °F) during this period.
