Patent ID: 6936473

Claim:
A method of preparing a biological sample for quantification which includes an element to be quantified said method comprising steps of collecting a volume of biological sample without quantifing the volume thereof to mix with a specified volume of an aqueous solution, measuring an absorptivity of an indicating material in the aqueous solution, measuring an absorptivity of the indicating material in the collected biological sample mixed with the specified volume of the aqueous solution, calculating a dilution ratio of the biological sample using the absorptivity of the indicating material in the specified volume of the aqueous solution and the absorptivity of the indicating material in said biological sample mixed with the specified volume of the aqueous solution, measuring an absorptivity of said element in the biological sample mixed with the specified volume of aqueous solution, and; obtaining a quantified value of said element in the biological sample using the measured absorptivity of said element and the calculated dilution ratio.
