      abstract     = {Advances in microscope stability, aberration correction and
                      detector design now make it readily possible to achieve
                      atomic resolution energy dispersive X-ray mapping for dose
                      resilient samples. These maps show impressive atomic-scale
                      qualitative detail as to where the elements reside within a
                      given sample. Unfortunately, while electron channelling is
                      exploited to provide atomic resolution data, this very
                      process makes the images rather more complex to interpret
                      quantitatively than if no electron channelling occurred.
                      Here we propose small sample tilt as a means for suppressing
                      channelling and improving quantification of composition,
                      whilst maintaining atomic-scale resolution. Only by knowing
                      composition and thickness of the sample is it possible to
                      determine the atomic configuration within each column. The
                      effects of neighbouring atomic columns with differing
                      composition and of residual channelling on our ability to
                      extract exact column-by-column composition are also
                      discussed.},
