To Control Ionization. 1  Ionization Voltage Typically, 70eV electrons from the filament are used for EI. 2  Emission Current The number of ions produced in unit time is proportional to the current of emitted electrons, i.e., emission current. 3  Ion Source Temperature The ion source is usually used at about 200 oC.
Typical values for equi-librium potentials in neurons are 70 mV for sodium and 100 mV for potassium. Because sodium is far from its equi-librium potential, there is a large driving force on sodium, sosodium ions move readily whenever a voltage-gated or lig-and-gated sodium channel opens in the membrane.
