Where budgets allow, basic research laboratories equip themselves with devices consisting of three or four sectors with collision cells distributed among the sectors. These mass spectrometers can perform high resolution mass spectrometry in tandem (see Chapter 5 on acquisition modes). This means their precision is at least four decimals in the m/z ratio of either the precursor ion and/or the daughter ions produced by collisions. ...
