The second-generation SYNAPT G2 platform from Waters provides a new dimension of performance to drive scientific discovery like never before. We’ve combined QuanTof – breakthrough quantitative Tof technology – and enhanced High Definition MS technologies to provide you with intuitive operation, application flexibility and a totally new level of performance for all your applications.
SYNAPT G2 HDMS is a high resolution exact mass MS/MS platform designed to get you to the right result, faster – no matter how challenging your application is. When you want to reach beyond the boundaries of conventional mass spectrometry, SYNAPT G2 High Definition Mass Spectrometry (HDMS) provides a new dimension to your discovery capability by combining high efficiency ion mobility based measurements and separations with high performance tandem mass spectrometry. By enabling you to differentiate samples by size, shape, and charge – as well as mass – this unique capability allows you to make discoveries that simply aren’t possible any other way.

Mass Scale Calibration Accuracy | The mass measurement accuracy of the instrument in High Resolution mode, using internal lock masses, 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 1 ppm over the range 150 to 900 m/z. |
Mass Measurement Accuracy | The mass measurement accuracy of the instrument, in High Resolution mode, will be better than 1 ppm RMS, based on 10 consecutive repeat measurements of the [M + Na]+ ion of raffinose (m/z 527.1588), using the [M + H]+ ions of leucine enkephalin (m/z 556.2771) and 4-acetamidophenol (m/z 152.0712) as the LockSpray lockmasses. Analyte and lockmass peaks must have sufficient intensity and be free of interference from other masses. |
Mass Range | The TOF mass range is 20 to 100,000 m/z in Resolution mode, and 20 to 32,000 m/z in High Resolution mode. The m/z transmission range for a quadrupole in non-resolving mode is 20 to 16,000 m/z for a 4000 m/z quadrupole, and 20 to 32,000 m/z for an 8000 m/z quadrupole. |
Acquisition Rate | Spectra can be acquired at a rate of 20 scans per second, except in pDRE mode, when the maximum rate is 10 scans per second. |
Dynamic Range | The dynamic range in High Resolution mode, defined as the range of peak intensities that will give better than 3 ppm accurate mass RMS for 10 sec of data without pDRE (programmable Dynamic Range Enhancement), is at least 4 orders of magnitude, when measured on the m/z 556.2771 peak from leucine enkephalin. |
High Mass Precursor Selection | Applicable to instruments with 8000 m/z and 32,000 m/z quadrupoles only. The low energy MS/MS spectrum of m/z 5569.1 from a solution of 2 μg/μL sodium iodide in 50/50 isopropanol/water will contain only m/z 5569.1 and its fragments. The intensity of the largest fragment ion will be less than 5% of the intensity of the precursor ion. MS/MS data will be acquired over the mass range 100 – 8000 m/z, with collision energy of 10 eV. |
