ABSTRACT:
A method and an apparatus which combines a linear two dimensional ion guide or a two dimensional ion storage device in tandem with a time-of-flight mass analyzer to analyze ionic chemical species generated by an ion source. The method improves the duty cycle, and therefore, the overall instrument sensitivity with respect to the analyzed chemical species.
