I'm in need of guidance regarding the conversion of my initial ICP-OES results, which were reported in mg/L, I conducted a dilution procedure on a 26.0 mg sample using a 1:3 mixture of nitric and hydrochloric acid, resulting in a total dilution volume of 0.025 dm^3.
My current data is in mg/L and is stored in an Excel spreadsheet. Despite my efforts to calculate the wt%, I'm still facing issues and would greatly appreciate assistance from anyone who can provide guidance on achieving accurate percentage conversions.
Hi Sheeraz,
To calculate the weight percentage from the concentration obtained on the ICP, you can apply this formula:
wt.% = ((Intial Conc. in mg/L X Vol. in L)/Mass in mg) x 100
For example, a sample with a concentration of 10.8 mg/L Al:
((10.8mg/L X 0.025L)/26.0mg) X 100 = 1.03 wt%
