Abstract
The present invention is directed to a method of preparing a biological sample for quantification which includes an element to be quantified. A volume of biological sample is collected without quantifying the volume thereof to mix with a specified volume of an aqueous solution. Absorptivity of an indicating material in the aqueous solution is measured. Absorptivity of the indicating material in the collected biological sample mixed with the specified volume of the aqueous solution is measured. Next, a dilution ratio of the biological sample is calculated using the absorptivity of the indicating material in the specified volume of the aqueous solution and the absorptivity of the indicating material in the biological sample mixed with the specified volume of the aqueous solution. Absorptivity of the element in the biological sample mixed with the specified volume of aqueous solution is measured and a quantified value of the element in the biological sample is obtained using the measured absorptivity of the element and the calculated dilution ratio.
