Sensitivity

Positive Electrospray (HESI): A 2 μL injection of a 500 fg/μL reserpine solution on a Thermo Scientific™ Hypersil GOLD™ aQ 20 x 2.1 mm 1.9 μm particle packed column at a flow rate of 300 μL/min 70/30 methanol/water with 0.05% formic acid will produce a minimum signal-to-noise ratio of 200,000:1 for the transition of the protonated molecule at m/z 609.3 to the fragment ion at m/z 195.1 when operated in selected-reaction monitoring (SRM) mode with Q1 and Q3 resolution set to 0.2 and 0.7 Da FWHM respectively.

Atmospheric Pressure Chemical Ionization (APCI): A 2 μL loop injection of a 500 fg/μL reserpine solution on a Thermo Scientific Hypersil GOLD aQ 20 x 2.1 mm 1.9 μM particle packed column at a flow rate of 300 μL/min 70:30 methanol/water with 0.05% formic acid will produce a minimum signal-to-noise ratio of 50,000:1 for the transition of the protonated molecular ion at m/z 609.3 to the fragment ion at m/z 19 5 .1 when operated in selected reaction monitoring (SRM) mode with Q1 and Q3 resolution both set to 0.7 Da FWHM.

Negative Electrospray (nESI): A 2 μL loop injection of a 500 fg/uL chloramphenicol solution will produce a minimum signal-to-noise ratio of 200,000:1 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 selected reaction monitoring mode (SRM) with Q1 and Q3 resolution set to 0.7 Da FWHM.

Mass Range: m/z 10 –1800

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 FWHM500 SRM/second (for any resolution from 0.2 through 2.0 FWHM)25msec polarity switching

Mass Stability: Mass assignment will be within ±0.05 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.
