How to fill out colorimetric estimation of and

How to fill out colorimetric estimation of and:

1. Start by preparing the sample: Make sure the sample is representative of the substance you want to measure. Take into account any necessary adjustments or dilutions.
2. Prepare the colorimetric reagent: Follow the instructions provided to prepare the colorimetric reagent according to the specified concentration or ratios.
3. Add the sample to the colorimetric reagent: Carefully combine the sample with the colorimetric reagent. Mix thoroughly to ensure proper reaction and obtain accurate results.
4. Set up the colorimetric measurement: Use a spectrophotometer or colorimeter to measure the absorbance or transmittance of the resulting solution. Follow the manufacturer's instructions for instrument calibration and parameter settings.
5. Perform blank correction: Record the absorbance or transmittance reading for a blank control, which contains all components of the sample except the analyte of interest. Subtract the blank value from the sample readings to account for any interfering substances or background absorbance.
6. Calculate the concentration of the analyte: Use the calibration curve or standard curve prepared with known concentrations of the analyte. Plot the absorbance or transmittance readings of the standards against their known concentrations. Determine the concentration of the analyte in the sample by interpolating the corresponding absorbance or transmittance value on the curve.
