Palladium Analysis -UV/Method

Palladium Analysis -UV/Method

Palladium Analysis -UV/Method

(OP)
I am looking for an alternative analysis for Palladium concentrations (in an acidic matrix) that are around 12ppm.  My current method is AA but due to other metals I analyze, I am concerned that I am plating up the internal parts of this instument.  The direct UV/measurement at this low level is detectible at such a low wavelength that it is not stable.  Can the Palladium be chelated with an NH3? If so, should it be saturated and what wavelength range should I scan?
