Abstract

In the time of flight mass spectrometer arrangement, ionization scheme is significant for the resolution perspective besides the other parameters. The scheme also contributes to improvement of the signal to noise ratio, particularly for low signal level. The ionization scheme along with the mass resolution was considered for the time of flight mass spectrometer with the three-field within the second order compensation. The double field is also provided. From the resolution obtained, triple and double field systems possess almost similar resolution with large ionisation region. When the triple system having better resolution with the small ionisation region is taken into account, the ionization scheme becomes significant for the field selection of the time of flight mass spectrometer..
