Objective Prepare standard samples from the standard solution of 100μg/mL and density 1.036 g/mL Take ICP of prepared standards Description Add experimental record here. Include what, how, and why... Data Concentration of standard (100 μg/mL)(1 mL/1.036)= 96.5ppm Stock solution of 1ppm made to be used for the ppb samples (1ppm)(50g)=(96.5ppm)(X) X= 0.51813g Actual Concentration of 1ppm Stock/Prepartation 0.514g of 96.5ppm standard water added to 50.3297g Actual Concentration: 985.5ppb Standard samples 250ppb 2.53939 g of 985.5 ppb stock solutions DI Water added till final mass 10.01435g Actual Concentration: 249.898ppb 500ppb 5.08262 g of 985.5 ppb stock solutions DI Water added till final mass 10.0242g Actual Concentration: 499.822ppb 2ppm 0.21780 g of 96.5ppm standard water added to 10.00803g Actual Concentration: 2.1001ppm 4ppm 0.44046g of 96.5ppm standard water added to 10.02064g Actual Concentration: 4.2417ppm 6ppm 0.66000g of 96.5ppm standard water added to 10.03525g Actual Concentration: 6.3466ppm 8ppm 0.83007g of 96.5ppm standard water added to 10.01051 Actual Concentration: 8.0018 10ppm 1.04895g of 96.5ppm standard water added to 10.02015g Actual Concentration: 10.1020ppm ICP Parameters Error creating thumbnail: Unable to save thumbnail to destination Error creating thumbnail: Unable to save thumbnail to destination Error creating thumbnail: Unable to save thumbnail to destination Error creating thumbnail: Unable to save thumbnail to destination Notes This area is for any observations or conclusions that you would like to note.
