The sample on the left was produced by spraying each metal twice and the one on the right just one pass (and the position of the Fe and Cu standards were reversed to conform with tradition). The next picture are the scans of the sample of the right (MH FeAlCsCo3) and has a map of the positions of the metals in the triagles which is different from standard practice. We did this to reduce the number of times one has to spray the substrate
