18 sie 2023 · I. Prepare the instrument and autosampler. Place the calibration solutions and the sample solutions in the auto sampler and record the position of each sample in your notebook. The auto sampler has a built in rack for ten 50 mL tubes (Positions 1-10) that are meant for standard solutions.

Let's say the ICP-OES software gives me a concentration of 186,49 ppm (mg/L) of Mn. I diluted the acid digested sample to 14.2 mL. I weighed in 10.17 mg of the powder I analyzed. I need to calculate the actual concentration.

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...
