How do you calculate dilution recipes for preparing an entire calibration curve from stock solutions? In this hands-on analytical chemistry tutorial, I demonstrate step-by-step calculations for preparing calibration standards at different concentration levels. Calibration concentrations covered: - 0.5 µg/L - 1 µg/L - 10 µg/L - 25 µg/L - 50 µg/L - 100 µg/L - 250 µg/L - 500 µg/L - 1,000 µg/L Topics covered: - Preparing intermediate standards from a concentrated stock solution -
