Methods to be Reviewed by OMB in 2016

where R = results expressed in mg/100g, C = concentration of the analyte in the injected solution in

ng/mL, V = volume of the initial extract in mL, S = sample weight in g, and D = dilution factor, the inverse

of any dilution made. All results were calculated on a ready to feed or reconstituted basis of 25 g

diluted to 225 g with water, except for SRM1849a that was calculated back to powder basis.
