ND means not detected. The sum of identified arsenic species in the prior four columns Percentage means the sum of four arsenic species quantified by HPLC-ICP-MS, relative to the total arsenic concentration in the same apple juice sample quantified by direct injection ICP-MS. The results in Table 3 are expressed as ug elemental arsenic/L. Say, however, that you wanted to know the amounts of each arsenic compound originally present in the juice sample. Assuming the solution analyzed in the ICP was created by diluting 1 mL of apple juice with 9 mL of dilute HNO3 solution a) Calculate the concentration (M) of each arsenic species present in the original apple juice sample for the entry corresponding to Juice 9. b) Calculate the grams of each arsenic species present in the original apple juice sample for the entry corresponding to Juice 9
