How to fill out spike recovery and mdl

How to fill out spike recovery and MDL:

1. Gather the necessary materials and instruments, including samples with known concentrations of analytes, reagents, standards, a spectrophotometer or other appropriate instrument, and a data analysis software.
2. Prepare a calibration curve using the samples with known concentrations. This can be achieved by measuring the signal response of each concentration and plotting it against the concentration values. Fit the data points to a curve and determine the equation of the line.
3. Spike the samples with known concentrations by adding a known amount of analyte to each sample. This will provide information on the recovery of the method.
4. Analyze the spiked samples and measure the signal response. Use the calibration curve equation to determine the concentration of the spiked analyte in each sample.
5. Calculate the recovery percentage by dividing the concentration obtained from the spiked sample by the expected concentration, then multiplying by 100.
6. Repeat the process for multiple spiked samples to ensure accuracy and precision of the method.
7. Document all the necessary information, including the concentrations used, the recovery percentages, and any other relevant observations or calculations.
