The series features the proprietary 19-mm MAX quadrupole mass filter. The quadrupoles are available in mass range options up to 16,000 amu with ppb detection capability and resolution characteristics that include a single detector capable of measuring neutrals, positive ions and negative ions.
The MAXIM-600P detector is based on the proprietary 6-mm triple quadrupole mass filter with pulse ion detection.
Waters' ZSPRAY LC-MS interface and quadrupole mass filter technologies will be combined with IonSpec's FT-MS technology.
The pressure in the ionizer is the same as in the rest of the surrounding vacuum, and also the same as in the quadrupole mass filter and ion detector.
In principle, the quadrupole ion trap (QIT) has an advantage over the quadrupole mass filter when large numbers of ions must be monitored.
Chapter two develops the theory of quadrupole storage mass spectrometry by first using the familiar quadrupole mass filter and applying this knowledge to develop the operational theory of quadrupole ion traps.
The MAXIM-600P detector is based around the proprietary 6-mm triple quadrupole mass filter with pulse ion detection.
Its ion optical system is optimized with a high-performance quadrupole mass filter and Shimadzu's Optdesign simulation program to provide high-quality mass spectra.
TOF systems' dynamic working range is typically six orders of magnitude, whereas quadrupole mass filter spectrometers typically go to eight orders of magnitude.
