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 Notes This area is for any observations or conclusions that you would like to note. Use categories like tags. Change the "Course" category to the one corresponding to your course. The "Miscellaneous" tag can be used for particular experiments, as instructed by your professor. Please be sure to change or delete this tag as required so that the categories remain well organized.
