The SYNAPT HDMS System can operator in two modes:
a) TOF mode
b) Mobility-TOF mode

TOF Mass Resolution in Positive Ion
a) V Mode: 10,000 measured on the (M + 6H)^6+ isotope cluster from bovine insulin (m/z 956)
b) W Mode: 17,500 measured on the (M + 6H)^6+ isotope cluster from bovine insulin (m/s 956)

TOF Mass Resolution in Negative Ion
a) V Mode: 10,000 measured on the (M - 4H)^4- isotope cluster from bovine insulin (m/z 1431)
b) W Mode: 17,500 measured on the (M - 4H)^4- isotope cluster from bovine insulin (m/z 1431)

Positive Ion MS Sensitivity
a) V Mode: The peak at m/z 556 from a solution of 50 pg/µL leucine enkephalin in 50/50 acetonitrile/water + 0.1% formic acid, infused at a flow rate of 5 µL/min, will have an intensity of greater than 1,700 counts per second. The instrument will be tuned to 10,000 resolution (as demonstrated on bovine insulin) and the mass range will be set to 1,000 Da.
b) EDC: The peak at m/z 556 from a solution of 10 pg/µL leucine enkephalin in 50/50 acetonitrile/water + 0.1% formic acid, infused at a flow rate of 5 µL/min, will have an intensity of greater than 2,000 counts per second. The instrument will be tuned to 10,000 resolution (as demonstrated on bovine insulin), with sensitivity set to a maximum at 556 Da.

Negative Ion MS Sensitivity:
V Mode: The peak at m/z 503 from a solution of 500 pg/µL raffinose in 70/30 acetonitrile/water (no additives), infused at a flow rate of 5 µL/min, will have an intensity of greater than 1,800 counts per second. The instrument will be tuned to 10,000 resolution (as demonstrated on bovine insulin), and the mass range will be set to 1,000 Da.

Positivt Ion MS/MS Sensitivity
V Mode: Using a [Glu]-Fibrinopeptide B solution of 100 fmol/µL, at a flow rate of 5 µL/min and with the instrument tuned for 10,000 resolution (as demonstrated on bovine insulin), the intensity of the most intense y" sequence ion from the MS/MS spectrum of the doubly charged precursor ion (785.8 Da) will be greater than 130 counts per second. This will correspond to a signal to noise ratio of greater than 50:1 (after a 3x9 smooth) on the most intense y" sequence ion, for a 1 second scan. The instrument mass range will be set to 2,000 Da.

Negative Ion MS/MS Sensitivity
V Mode: Using a solution of 500 pg/µL raffinose in 70/30 acetonitrile/water, at a flow rate of 5 µL/min and with the instrument tuned for 10,000 resolution (as demonstrated on bovine insulin), the intensity of the fragment ion at 179.1 Da in the MS/MS spectrum of the precursor ion at 503.2 Da will be greater than 130 counts per second. The instrument mass range will be set to 1,000 Da.

Mass Scale Calibration Accuracy
The mass measurement accuracy of the instrument in V-mode, using an internal lockmass, is such that the RMS error between the measured and the accepted masses of peaks which have sufficient intensity, and are free from interference from other masses, will be less than 2 ppm over the range of 150-900 Da.

Mass Measurement Accuracy
The mass measurement accuracy of the instrument, in W-mode, will be better than 2 ppm RMS, based on 10 consecutive repeat measurements of the [M + Na]^+ ion of raffinose (m/z 527.1588), using the [M + H]^+ ion of leucine enkephalic (556.2771) as the LockSpray lockmass. Analyte lockmass peaks must have sufficient intensity and be free of interference from other masses.

MassRange
The TOF mass range is 20 - 100,000 Da in V-mode, and 20 - 26,500 Da in W-mode.
The quadrupole mass range in non-resolving mode is 20 - 16,000 Da for a 4,000 Da quadrupole, and 20 - 32,000 Da for an 8,000 Da quadrupole.
