Caffeine was analyzed using UV-Vis spectroscopy. The average absorbance for 10 blanks is 0.01826. The standard deviation from the measurement is 0.00101. The slope of the calibration curve is 1.75 × 109 M−1. Calculate the signal detection limit, concentration detection limit and limit of quantification.
