Product description
3. 10 g of meat, having a moisture content of 73%, was dried to an air-dry state, homogenized, compressed into a tablet. Then it was carried out the determination of copper using X-ray fluorescence analysis. Construct a graph of the dependence of J - Jf on the concentration of copper according to the following data:
Sample number 1 2 3 4 5
Copper content, µg/g dry matter 2.4 3.4 6.0 8.3 CX
Intensity, J imp/s 339 437 696 927 547
Background intensity, Jph pulse/s 99 103 109 115 105
Determine the copper content of the sample in µg/g and as a percentage.
