To verify sensitivity for 6130 and 6140 Quads - G1978B Multimode, Positive SIM Modes

When the method is finished, a report prints showing the signal-to-noise ratio
for the five blank and five sample peaks, and a blank-subtracted average of the
sample peaks. The blank-subtracted average signal-to-noise value must be
greater than or equal to 20:1 peak-to-peak (100:1 RMS).

Preparation
1 Transfer 1 mL of 5 ng/µL reserpine (Agilent G2423A) to a 50 mL volumetric
2 Dilute to the 50 mL mark with 75:25 methanol/water with 5 mM ammonium
3 Transfer 1mL of the first dilution to a 100 mL volumetric flask. Use a clean
4 Dilute to the 100 mL mark with 75:25 methanol/water with 5 mM
5 Transfer approximately 1 mL of the second dilution to an autosampler vial.
