Web14 feb. 2024 · Many laboratories now use matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS) by direct plating or cell lysis for the identification of GBS isolates. The cell lysis step increases time to results for clinical samples and is more complex to perform. WebThe TOF measurement procedure is also ideally suited to the MALDI ionization process since the pulsed laser takes individual 'shots' rather than working in continuous operation. MALDI-TOF instruments are …

WebThe ions are analyzed with a Time-of-Flight Mass Spectrometer (ToF MS). Using this technique, the mass of the ions is determined by separation of the ions in time according … Web21 dec. 2024 · As in a standard TOF instrument, the TOF mass analyser measures the time that it takes for these ions to ‘fly’ from one side of the drift tube to the other and hit the detector; the flight time is proportional to the mass-to-charge (m/z) ratio (Fig. 1). The manufacturer’s specifications of the LM2X-TOFMS are given in Table 1.
