Abstract (en)
[origin: WO2006029999A2] A device for producing an ion beam (120) from positively charged ions in an evacuated flight time mass spectrometer (10) containing an ion source (12), an interface (14) for transferring the ion beam of atmospheric pressure into the mass spectrometer (10), and an ion extraction device (64) with a voltage source (74) for the production of a negative potential difference between the ion extraction device (64) and the ion source (12), characterized in that the negative potential difference amounts to at least one - 1 kV and the ion extraction device (64) is connected to the voltage source (74) via a high ohm resistor (72), the value of which is selected in such a way that no spontaneous discharge occurs between the ion source (12) and ion extraction device (64) when voltage is applied.
