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.
