Sample and Standard Preparation procedures for Trace Elements in Lead

[1] Preparation of Lead (Pb) Samples: Drill Pb metal to make small pieces. Weigh 2.0 grams of these pieces on a balance. Place the sample in a 400ml Pyrex breaker and add 10ml H2O, 2.5 grams of tartaric acid and 7ml HNO3. Warm on a hot-plate until the sample dissolves. Dilute to 100ml in a volumetric flask with water (H2O). This prepares a 2% sample solution, with a dilution factor of 50.
