Measuring Indium Concentrations

EpiGen

I am undergoing a research term at my university working with photovoltaics. We are required to measure the concentration of Indium after doing copper etching processes with CIGS films. We've considered absorption spectroscopy but it will be weeks until we have the parts necessary to use this method and I would like to start sooner. Does anyone have any other methods or ideas? Thank you very much!

Xray fluorescence and SIMS should both work if you have access to the equipment.

Thanks! Are there any others?

Wet Analysis could be another way out.

but unfortunately it requires bit more workout than those formerly described by phyzguy!!
