Samples were dried onto Zn metal plates then analysed. Even concentration across the dried sample as improved by drilling small pockets/wells into the metal surface. Zn was chosen due to its comparatively simple spectrum and lack of interferences to Cs. Samples showed significant self absorption, however low detection limits were possible in both Urine and Blood samples
