How do you prepare standard solutions for calibration curve?
To prepare the standards, pipette the required amount in the volumetric flask. Then fill the flask to the line with solvent, and mix. Continue making the standards by pipetting from the stock solution and diluting. For a good calibration curve, at least 5 concentrations are needed.- Standard solution: A solution of accurately known concentration, prepared using standard substances. Often with a concentration of 1000ppm of analyte (e.g. 1000ppm Fe) and purchased with a certificate.6 mar. 2017
