<p>A method of analysing ions is disclosed comprising performing an initial multi- dimensional survey scan comprising separating parent ions according to a first physico- chemical property and separating the parent ions according to a second physico-chemical property. At least one parent ion of interest from the initial multi-dimensional survey scan is determined, the at least one parent ion of interest having a first value or range of the first physico-chemical property and a second value or range of the second physico-chemical property. Then,during a subsequent single cycle of separation, the method further comprises separating parent ions according to the first physico-chemical property.If the parent ions have a value or range of the first physico-chemical property which corresponds with the first value or range, then the method further comprises selecting parent ions of interest having a value or range of the first physico-chemical property which corresponds with the first value or range and which also have a value or range of the second physico- chemical property which corresponds with the second value or range. If the parent ions have a value or range of the first physico-chemical property which does not correspond with the first value or range then the method further comprises separating the parent ions according to the first physico-chemical property and separating the parent ions according to the second physico-chemical property.</p> |
